Let’s learn these SAT math topics of Heart of Algebra, one by one.
Number System
In number system of SAT Algebra syllabus, you need to learn the concepts of number line, classification of numbers such as natural numbers, whole numbers, integers, rational and irrational numbers, real numbers etc.
Number Line
A straight line on which the numbers are represented is called as Number Line. On this number line, there is a negative side, zero, and positive side.
All the numbers to the left of 0 are negative numbers and all the numbers to the right of 0 are all positive numbers.
Thus, you can say the numbers present on the right are larger than the numbers on their left.
Natural Numbers
Natural numbers are the counting numbers and it is right side of zero on number line.
Natural numbers are positive integer which starts from 1 to infinity.
The first 100 natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99 and 100.
Whole Numbers
Whole numbers are the counting numbers and it is also right side of zero on number line.
Whole numbers are nonnegative integer which starts from 0 to infinity.
All SAT Math Formulas : Integers
An integer is a number in which there is NO fractional or decimal part. The integers can be positive or negative. The set of integers includes positive integers, negative integers and zero.
The zero has no sign, it mean zero is neither positive nor negative.
Positive Integers
A positive integer is the numbers in the right side of zero on number line. The positive integers are also called as natural numbers.
Negative Integers
A negative integer is the numbers in the left side of zero on number line. The negative integers are negative of the natural numbers.
Consecutive Numbers
Consecutive numbers or integers is a group of numbers that follows a regular counting order or pattern where the difference between any two consecutive number is fixed.
For example: 1, 2, 3 are three consecutive numbers, 53,54, 55, 56, 57 are five consecutive numbers.
The number immediately before a number is called its predecessor. The number immediately after a number is called its successor.
Consecutive Numbers Formula
If n is the first number, then other consecutive numbers are (n + 1), (n + 2), (n + 3), … etc.
Even consecutive numbers formulas are 2n, (2n + 2), (2n + 4), (2n + 6), etc.
Even consecutive numbers formulas are (2n + 1), (2n + 3), (2n + 5), (2n + 7), etc.
Rational Numbers
A rational number that can be written in the form of p/q, where p and q are integers and q is not equal to 0.
For example: 1/2, 3/4 5/7 etc.
A fraction is a part of whole.
Therefore, a rational number can be positive or negative but a fraction is always positive.
In decimal expansion of rational number, a rational number is a terminating or nonterminating with recurring decimals numbers.
Irrational Numbers
An irrational number that is not a rational number. It means, an irrational number cannot be written in the form of ratio of integers.
For example: √2 and √3 etc. are irrational.
In decimal expansion of irrational number, an irrational number is a nonterminating or nonrecurring decimals numbers.
Real Numbers
A real number is a set of rational and irrational numbers. All the numbers represented on number line are called real numbers.
For example: 3/5, 8/11, 12, 9, √2 and √3 etc. are real numbers.
Imaginary Numbers
An imaginary number is a number which is NOT a real number and hence it cannot be represented on number line.
The square of a real number is always positive whereas the square of an imaginary number is always negative.
The imaginary numbers are written as a real number multiplied with “i”, where “i” stands for IOTA and i = √(1) or i^{2} = 1.
For example: 3i, 5i, (7/2)i etc.
Complex Numbers
A complex number is a combination of a real number and an imaginary number.
Hence, the complex number can be written in form of (a + bi), where “a” is a real part and “b” is an imaginary part.
For example: 1 + 3i, 5 + 8i, 3 – 6i etc.
Basic Algebra
In basic algebra of SAT Algebra syllabus, you need to learn the variables, constants, algebraic expression, order of operations, and algebraic identities.
Variables
A variable is an alphabet letter which represents an unknown value in algebra whose value can be found by performing algebraic operations.
For example: in the equation a + b = 5, a and b are variables.
When an equation includes a variable, which makes the equation is called solution to that equation.
Algebraic Expression
An algebraic expression is a mathematical statement in which variables, coefficient, constants and mathematical operators are there. For example: 12x + 5y + 9 is an algebraic expression in which 12 is coefficient of x, 5 is coefficient of y, 9 is a constant and “+” is a mathematical sign.
PEDMAS or Order of Operation
The PEDMAS is a concept that help us to simplify the math problems containing more than one mathematical operators. PEDMAS is an acronym whose full form is as below.
P → Parentheses ( ), { }, [ ]

E → Exponent or Index

D → Division (÷)

M → Multiplication (x)

A → Addition (+)

S → Subtraction ()

For example: You need to simplify 2 – (12 x 3 + 5 – 6). What are the order of operations to be performed first; first we add or first we multiply or subtract? Hence, you need to use PEDMAS.
Simplifying Algebraic Expression
To simplify an algebraic expression, you need to combine the like terms. Like terms in algebraic expression are added or subtracted.
For example: 3x^{3 }+ 4x^{2 }− 2x^{3 }+ 7x − x^{2 }+ 10 − 2x = (3x^{3 }− 2x^{3}) + (4x^{2 }− x^{2}) + (7x − 2x) + 10 = x^{3 }+ 3x^{2 }+ 5x + 10.
Algebraic Identities
To solve algebra questions, you need to learn algebraic identities. There are following algebraic identities.
 (a + b)^{2} = a^{2} + 2ab + b^{2}
 (a – b)^{2} = a^{2} – 2ab + b^{2}
 (a + b)(a – b) = a^{2} – b^{2}
 (a + b + c)^{2} = a^{2} + b^{2} + c^{2} + 2ab + 2bc + 2ca
 (a + b – c)^{2} = a^{2} + b^{2} + c^{2} + 2ab – 2bc – 2ca
 (a – b + c)^{2} = a^{2} + b^{2} + c^{2} – 2ab – 2bc + 2ca
 (a – b – c)^{2} = a^{2} + b^{2} + c^{2} – 2ab + 2bc – 2ca
 ( a + b + c)^{2} = a^{2} + b^{2} + c^{2} – 2ab + 2bc – 2ca
 (a + b)^{3} = a^{3} + b^{3} + 3ab(a + b)
 (a – b)^{3} = a^{3} – b^{3} – 3ab(a – b)
 a^{3} + b^{3} = (a + b)^{3} – 3ab(a + b) = (a + b)(a^{2} – ab + b^{2})
 a^{3} – b^{3} = (a – b)^{3} + 3ab(a – b) = (a – b)(a^{2} + ab + b^{2})
 a^{3} + b^{3} + c^{3 }– 3abc = (a + b + c)(a^{2} + b^{2} + c^{2 }– ab – bc – ca)
 If (a + b + c) = 0, then a^{3} + b^{3} + c^{3 }= 3abc
Slope of Line
In slope of line of SAT Algebra syllabus, you need to learn finding the slope of a line, slopes of parallel lines and perpendicular lines, slopeintercept form of line, point slope of line, intercept form of line etc.
Slope of Line
The slope of a line that contains the point A(x_{1}, y_{1}) and B(x_{2}, y_{2}) is defined as
Slope (m) = Rise / Run = (Change in y) / (Change in x) = (y_{2} – y_{1}) / (x_{2} – x_{1})
Slope of Horizontal and Vertical Line
When a line becomes horizontal, then the rise is zero, so the slope (m) = Rise / Run = 0. Hence, the slope of a horizontal line is zero.
When a line becomes vertical, then the run is zero, so the slope (m) = Rise / Run → ∞. Hence, the slope of a vertical line is infinity.
Parallel and Perpendicular Lines
If the line l_{1} has slope m_{1} and the line l_{2} has slope m_{2}, then the lines l_{1} and l_{2} are parallel if m_{1} = m_{2}.
If the line l_{1} has slope m_{1} and the line l_{2} has slope m_{2}, then the lines l_{1} and l_{2} are perpendicular if m_{1}m_{2} = 1.
Equation of a Line in Slope Intercept Form
If a line L makes an intercept length as b on yaxis with the slope m, then the line is in slopeintercept form and hence its equation is y = mx + b.
Equation of a Line in Point Slope Form
If a line L with the slope m and passes through the point (x_{1}, y_{1}), then the line is in pointslope form and hence its equation is y – y_{1} = m(x – x_{1}).
Equation of a Line in Intercept Form
If a line L makes intercepts on both axes as a and b, then the equation of a line x/a + y/b = 1.
Equation of a Line in Standard Form
The standard form of equation of a line is ax + by + c = 0.
Linear Equations
In linear equation of SAT Algebra syllabus, you need to learn how to solve system of linear equations using elimination method, substitution method, cross multiplication method, graphical method and how to find number of solutions without solving the system of linear equations and word problems based on system of linear equations etc.
Linear Equations
An equation whose the degree of the variables is always 1 is known as linear equations. A linear equation is also called a onedegree equation.
Linear Equations in One Variable
A linear equation in which there is only one variable is known as linear equations in one variable. The standard form of linear equation in one variable is ax + b = 0, where x is a variable, a is coefficient of x and b is a constant term. For example: 3x + 6 = 0, 5x + 9 = 0 etc.
How to Solve Linear Equations in One Variable
To solve a linear equation in one variable, you need to perform the algebraic operation on both sides of the equation so that the variable is left on one side and all other terms in other side. Now, this value of x is the solution of the linear equation in one variable. Let’s understand with an example.
For example:
Solve 4x + 8 = 0.
Solution:
4x + 8 = 0
⇒ 4x = 8
⇒ x = 8/4
⇒ x = 2 is the solution of the given equations.
Linear Equations in Two Variables
A linear equation in which there are two variables is known as linear equations in two variables. The standard form of linear equation in two variable is ax + by + c = 0, where x and y are variables, a is coefficient of x, b is coefficient of y and c is a constant term.
For example: 3x + 6y + 11 = 0, 5x + 9y – 8 = 0 etc.
System of Linear Equations in Two Variables
A system of linear equations in two variables is of the form as below.
a_{1}x + b_{1}y + c_{1} = 0 and a_{2}x + b_{2}y + c_{2} = 0
Solving System of Linear Equations in Two Variables
To solve the system of linear equations in two variables as a_{1}x + b_{1}y + c_{1} = 0 and a_{2}x + b_{2}y + c_{2} = 0, there are three methods: elimination method, substitution method, cross multiplication method, graphical method.
Solving System of Linear Equations in Two Variables by Elimination Method
To solve the system of linear equations in two variables as a_{1}x + b_{1}y + c_{1} = 0 and a_{2}x + b_{2}y + c_{2} = 0 by elimination method, you need to equate the coefficients of any one variable and then eliminated by adding or subtracting the equations. After elimination, the final equation is of the form of linear equation in one variable which is very easy to solve by algebraic operations on both sides.
To understand the elimination method of solving system of linear equations, let’s solve the equations as below.
For example: Solve the system of equations as
Equation 1: 2x + 3y = 8
Equation 2: 3x + 2y = 7
From 2 × (Equation 1) – 3 × (Equation 2), you get
(4x + 6y) – (9x + 6y) = 16 – 21
⇒ 5x = 5
⇒ x = 1
Now, from Equation 1, you get
2(1) + 3y = 8
⇒ 3y = 8 – 2
⇒ 3y = 6
⇒ y = 6/3
⇒ y = 2
Hence, x = 1 and y = 2 are the solutions of given equation.
Solving System of Linear Equations in Two Variables by Substitutions Method
To solve the system of linear equations in two variables as a_{1}x + b_{1}y + c_{1} = 0 and a_{2}x + b_{2}y + c_{2} = 0 by substitution method, you need to find the value of one variable in terms of other variable from any one of the equation and then put this value in other equation. After this substitution, you will get a linear equation in one variable, which is very easy to solve by algebraic operations on both sides.
To understand the substitution method of solving system of linear equations, let’s solve the equations as below.
For example: Solve the system of equations as
Equation 1: 2x + 3y = 9
Equation 2: x – y = 3
From Equation 2, you get x = y + 3.
Now, put this value of x in Equation 1,
2(y + 3) + 3y = 9
⇒ 2y + 6 + 3y = 9
⇒ 5y = 3
⇒ y = 3/5 and then x = y + 3 = 3/5 + 3 = 18/5
Hence, x = 18/5 and y = 3/5 are the solution of given equations.
Solving System of Linear Equations in Two Variables by Cross Multiplication Method
To solve the system of linear equations in two variables as a_{1}x + b_{1}y + c_{1} = 0 and a_{2}x + b_{2}y + c_{2} = 0 by cross multiplication method, you need to do following steps.
Number of Solutions of System of Linear Equations in Two Variables
The standard form of linear equations is
a_{1}x + b_{1}y + c_{1} = 0
a_{2}x + b_{2}y + c_{2} = 0
For Unique Solution (Only One Solution) or Consistent System of Equations, in this case the graph of the linear equations is intersected lines.
Required condition to be Unique solution is
For No Solution or Inconsistent System of Equations, in this case the graph of the linear equations is parallel lines.
Required condition to be No solution is
For Many Solution or Consistent System of Equations, in this case the graph of the linear equations is coincident lines.
Required condition to be Many solution is

Functions
In functions of SAT Algebra syllabus, you need to learn about linear functions, compositions of functions, rate of change and absolute value functions.
Linear Functions
A linear function is a linear polynomial of the form of (ax + b). The graph of a linear function is always a straight line. The linear function is denoted by f(x), g(x) or p(x) etc.
For example: f(x) = 3x + 5, g(t) = 9t – 11/5 etc.
Value of Linear Functions
The value of linear function f(x) = ax + b at x = k is when x is substituted with k in the linear function. It mean, the value of f(x) = ax + b at x = k is f(k) = ak + b.
For example: if f(x) = 9x – 7, then the value of the function at x = 2 is f(2) = 9(2) – 7 = 18 – 7 = 11.
Composition of Functions
The composition of functions is a composition of two functions in which the output of one function is the input for the second function.
The composition of functions f(x) and g(x) is fog(x) = f(g(x)) or gof(x) = g(f(x)).
For example:
If f(x) = 2x + 3 and g(x) = 5x – 7, then
fog(x) = f(g(x)) = 2(g(x)) + 3 = 2(5x – 7) + 3 = 10x – 14 + 3 = 10x – 11
gof(x) = g(f(x)) = 5(f(x)) – 7 = 5(2x + 3) – 7 = 10x + 15 – 7 = 10x + 8
Average Rate of Change of Functions
The average rate of change of function y = f(x) on an interval x ∈ [a, b] is the measure of rate of changes of the variable y with respect to change of x.
Average Rate of Change of Linear Functions
Since the graph of a linear function is a straight line, then its average rate of change of a linear function y = f(x) is as below.
Thus, for a linear function y = ax + b, the average rate of change of linear function is slope of the line.
For example: in the equation of line y = 5x + 9, the rate of change is its slope which is equal to 5.
Average Rate of Change of Nonlinear Functions
Since the graph of a nonlinear function y = f(x) is not a linear, so in that case, the average rate of change of a nonlinear function f(x) on an interval [a,b] is the slope of the secant line.
Absolute Value of Number
Absolute value of a number is its distance from zero on number line. The absolute value of a real number x is denoted by x.
For example: The number 5 is at a distance of 5 units from 0 and 5 is at a distance of 5 units from 0. Thus, 5 = 5 and 5 = 5
Absolute Value Functions
The absolute value function y = x is defined as below.
For x ≥ 0, y = x = x , and
For x < 0, y = x = x
Inequalities
In inequalities of SAT Algebra syllabus, you need to learn about intervals, linear inequalities, quadratic inequalities, absolute value inequalities.
What are Inequalities and Inequations?
The signs of < (Less than), ≤ (Less Than or Equal To), > (Greater Than), ≥ (Greater Than or Equal To) are called inequality and a mathematical statement which contains sign <, ≤, >, ≥ is called an inequation.
The inequality defines the comparison between two numbers or two mathematical statements
For example: 5x + 6 > 10, 3x/2 – 9 ≤ 5 etc.
Intervals
There are following types of intervals.
Open Interval : x ∈ (a, b) ⇒ a < x < b ⇒ x can take all real values after “a” till before “b”.
Close Interval : x ∈ [a, b] ⇒ a ≤ x ≤ b ⇒ x can take all real values from “a” to “b”.
Left Open Right Closed Interval : x ∈ (a, b] ⇒ a < x ≤ b ⇒ x can take all real values after “a” to “b”.
Left Close Right Open Interval : x ∈ [a, b) ⇒ a ≤ x < b ⇒ x can take all real values from “a” till before “b”.
Left Open Right Unbounded : x ∈ (a, ∞) ⇒ x > a ⇒ x can take all real values after “a” tending to infinity.
Left Close Right Unbounded : x ∈ [a, ∞) ⇒ x ≥ a ⇒ x can take all real values from “a” tending to infinity.
Left Unbounded Right Open : x ∈ (∞, b) ⇒ x < b ⇒ x can take all real values before “b”.
Left Unbounded Right Close : x ∈ (∞, b] ⇒ x ≤ b ⇒ x can take all real values till “b”.
Properties of Inequalities
For all real numbers a, b and c , the following are true.
Transitive Property: If a < b and b < c, then a < c.
Addition and Subtraction Property: If a < b, then a + k < b + k and a – k < b – k.
Multiplication and Division Property: If a < b and k is positive, then ak < bk and a/k < b/k.
If a < b and k is negative, then ak > bk and a/k > b/k.
Solving Inequalities
Solving inequalities is same as solving equations with one very important exception that whenever you multiply or divided both sides by a negative number, then the inequality sign will be reversed. And, use all the properties of inequalities.
Solving Linear Inequalities in One Variable
Linear inequalities in one variable are of the following forms.
ax + b > 0,
ax + b ≥ 0,
ax + b < 0,
ax + b ≤ 0.
Solving linear inequalities of one variable is same as the solving equation with doing algebraic operations and represent the solution of inequations using intervals or on number line.
Solving Linear Inequalities in Two Variables
Linear inequalities in two variables are of the following forms.
ax + by > c,
ax + by ≥ c,
ax + by < c,
ax + by ≤ c.
Now, the solution of linear inequalities in two variables is done by using graphing the linear inequalities.
The solution of the linear inequality of the form of ax + by > c contains all the points on the shaded region as below. In this solution, the solution of ax + by = c is excluded, hence the graph of ax + by = c is represented as dotted line.
The solution of the linear inequality of the form of ax + by ≥ c contains all the points on the shaded region as below. In this solution, the solution of ax + by = c is included, hence the graph of ax + by = c is represented as solid line.
The solution of the linear inequality of the form of ax + by < c contains all the points on the shaded region as below. In this solution, the solution of ax + by = c is excluded, hence the graph of ax + by = c is represented as dotted line.
The solution of the linear inequality of the form of ax + by ≤ c contains all the points on the shaded region as below. In this solution, the solution of ax + by = c is included, hence the graph of ax + by = c is represented as solid line.
Solving System of Linear Inequalities in Two Variables
In solving the system of linear inequalities, you need to draw the regions of solutions of both linear inequalities as discussed above and then the solutions of linear inequalities is the intersection of the regions of both solutions region.
ax + by > c,
ax + by ≥ c,
ax + by < c,
ax + by ≤ c.
To understand better, let’s solve one example.
For example: Solve the system of inequalities of inequalities y ≤ x – 2 and y > 3x + 5.
First, draw the solution region of the inequality y ≤ x – 2 and then draw the solution region of the inequality y > 3x + 5.
Now, the intersection of both region is the solution region of both the given inequalities.
Absolute Value Inequalities
The solution of absolute value inequalities is done by following rules.
 If x < a, then a < x < a.
 If x ≤ a, then a ≤ x ≤ a.
 If x > a, then x < a or x > a.
 If x ≥ a, then x ≤ a or x ≥ a.
 If ax + b < c, then c < ax + b < c ⇒ c – b < ax < c – b ⇒ (c – b)/a < x < (c – b)/a
 If ax + b ≤ c, then c ≤ ax + b ≤ c ⇒ c – b ≤ ax ≤ c – b ⇒ (c – b)/a ≤ x ≤ (c – b)/a
 If ax + b > c, then ax + b < c or ax + b > c ⇒ ax < c – b or ax > c – b ⇒ x < (c – b)/a or x > (c – b)/a
 If ax + b ≥ c, then ax + b ≤ c or ax + b ≥ c ⇒ ax ≤ c – b or ax ≥ c – b ⇒ x ≤ (c – b)/a or x ≥ (c – b)/a
Quadratic Inequalities
Quadratic inequalities are of the following forms.
ax^{2} + bx + c > 0,
ax^{2} + bx + c ≥ 0,
ax^{2} + bx + c < 0,
ax^{2} + bx + c ≤ 0.
To solve these quadratic inequalities, first you need to find the roots of the quadratic equation ax^{2} + bx + c = 0 and then write the quadratic equation as product of its two factors.
Let α and β are the roots of quadratic equation.
Then, ax^{2} + bx + c = a(x – α)(x – β), where a > 0.
Now, you need to solve the quadratic inequalities as below.
(x – α)(x – β) > 0,
(x – α)(x – β) ≥ 0,
(x – α)(x – β) < 0,
(x – α)(x – β) ≤ 0.
Now, the solution of quadratic inequalities is done by using following rules.
 If (x – α)(x – β) < 0, then α < x < β.
 If (x – α)(x – β) ≤ 0, then α ≤ x ≤ β.
 If (x – α)(x – β) > 0, then x < α or x > β.
 If (x – α)(x – β) ≥ 0, then x ≤ α or x ≥ β.

Let’s learn these SAT math topics of Problem Solving Data Analysis, one by one.
Ratios and Proportions
In ratio and proportions of SAT Data Analysis syllabus, you need to learn the concepts of ratios, rates and proportions.
Ratios
A ratio is a comparison of two quantities of same units by their division.
If a and b are two quantities of same unit, then the ratio can be a : b or a/b.
For example: Ratio of 3 kg to 300 gm is 3kg / 300 gm = 3000 / 300 = 10 / 1 = 10 : 1.
If a number x is divided into the ratio a : b, then first number is ax/(a + b) and other quantity is bx/(a + b).
For example:
If 100 is divided into ratio of 13 : 12, then
the first number is 100 × 13 / (13 + 12) = 100 × 13 / 25 = 4 × 13 = 52
the second number is 100 × 12 / (13 + 12) = 100 × 12 / 25 = 4 × 12 = 48
Rates
A rate is a comparison of two quantities of different units by their division.
For example: If a car is running a distance of 120 km in 2 hours, then its rate is 120 km / 2 hour = 60 km/hour.
Proportions
An equality of ratios is known as proportion.
If the ratios a / b and c / d are equal, means a / b = c / d, then a, b, c, d are in proportion.
If four numbers a, b, c, d are in proportion, then first and last numbers a and d are extremes and second and third numbers b and c are means.
Since four numbers a, b, c, d are in proportion, then a/b = c/d ⇒ ad = bc ⇒ Product of Extremes = Product of Means.
Percentage
In percentage of SAT Data Analysis syllabus, you need to learn the concepts of percentage, percentage of change.
Percent
A percent means per “cent”, it means a quantity in per 100 is called percent.
For example: if a student get 85 marks in his test of 100 marks, then the percent of marks obtained by student is 85%.
To convert a percentage into fraction or decimal, remove the percentage (%) sign and divide the number by 100 and then simplify it.
For example: 50% = 50/100 = 1/2, 45% = 45/100 = 0.45 etc.
To convert a fraction or a decimal into percentage, multiply the fraction or decimal with 100 and put the sign of percentage (%) with it.
For example: 3/4 = (3/4 × 100)% = 75%, 12/5 = (12/5 × 100)% = 240%.
Percentage of Change
When a quantity increases or decrease from its original amount, then this called increase or decrease and if the increase or decrease is converted into percentage, then it is known as percentage of change.
Percentage Increase = (Amount of Increasing / Original Amount ) × 100 %
Percentage Decrease = (Amount of Decreasing / Original Amount ) × 100 %
Word Problems on Percentage
In the word problems of percentage, there is an equation is formed as below.
Let x% of M is N. Then, the equation is M × x / 100 = N.
Out of these three quantities, two quantities are known and one of them is unknown.
Thus, you need to ask three types of questions.
 Finding the percent of an amount (Find N)
 Finding the percentage (Find x)
 Finding the whole (Find M)
Statistics
In statistics of SAT Data Analysis syllabus, you need to learn the concepts of mean, median, mode and range. Mean, median and mode are known as three measures of central tendency in statistics.
Mean
A mean of a data set is the sum of all observations divided by the number of observations. The mean is also known as arithmetic mean or average.
Median
A median of a data set is the middlemost observation when the the observations are arranged in ascending or descending order.
If the number of observations in the set is odd, then there is only one middlemost observation, hence this middlemost is the median.
If the number of observations in the set is even, then there are two middlemost observations, hence the mean of these middlemost observations is the median.
Mode
A mode of a data set is the observation which has highest frequency. Some set of data have more than one mode, and others have no mode.
Range
In a data set, the difference between the highest value observation and lowest value observation is known as range of the data set.
For example: Find the mean, median, mode, and range of the data set {132, 149, 152, 164, 164, 175}.
Mean = (132 + 149 + 152 + 164 + 164 + 175) / 6 = 156
Since the data set is already in ascending order and the number of observations is even, hence its middlemost observations are 152 and 164. Hence,
Median = (152 + 164) / 2 = 158
Since the observation 164 repeats two times, then 164 has highest frequency.
Mode = 164
In the data set, 132 is the lowest and 175 is the highest value. Then,
Range = 175 – 132 = 43
Probability
In probability of SAT Data Analysis syllabus, you need to learn about the definition of probability, mutually exclusive events, dependent and independent events, addition rules of probability, product of probability, mutually exclusive events, dependent and independent events probability etc.
Definition of Probability
In our daily life, many events cannot be predicted you can measure only the chance of an event to occur. Thus, the probability is a measure of the likelihood of an event to occur.
In a trial, an outcome is one of the possible results that can occur as a result of a trial. Thus, the probability of an even A is denoted as P(A) and it is defined as
Mutually Exclusive Events
Two events which do not occur simultaneously known as mutually exclusive events.
If A and B are mutually exclusive events, then P(A ∩ B) = 0
Dependent Events
Two events in which the occurrence of one event affect the occurrence of other known as dependent events.
If A and B are dependent events such that the event A is already occurred, then P(A ∩ B) = P(A) × P(B/A) and when the event B is already occurred, then P(A ∩ B) = P(B) × P(A/B).
Independent Events
Two events in which the occurrence of any event does not affect the occurrence of other known as independent events.
If A and B are independent events P(A ∩ B) = P(A) × P(B).
Addition Rule of Probability
If A and B are events, then the probability of occurrence of event A or B or both is
P(A or B) = P(A ∪ B) = P(A) + (B) – P(A ∩ B)
If A and B are mutually exclusive events [ P(A ∩ B) = 0 ], then
P(A or B) = P(A ∪ B) = P(A) + P(B)
Product Rule of Probability
If A and B are independent events, then the probability of occurrence of event A and B is
P(A and B) = P(A ∩ B) = P(A) × P(B)
If A and B are dependent events, then the probability of occurrence of event A and B is
P(A and B) = P(A ∩ B) = P(A) × P(B/A)
Unit Conversion
In unit conversion of SAT Data Analysis syllabus, you need to learn how to convert of some units.
You can use conversion factors to convert a unit of measure from one system to another. Sometimes you may need to use two or more conversion factors
Volume Conversion
Volume is the total amount of space that is covered by an object which can be solid or hollow. The unit of volume is cubic units like cm^{3}, m^{3}.
Capacity Conversion
Volume is the total amount of space that is covered by an object which can be hollow only. The unit of volume is cubic units like litre, gallons, etc.
Capacity to Volume Conversion
The conversion of litre to cm^{3} is 1 litre = 1000 cm^{3}.
Formulas to Remember for SAT : Density
Density is a measure of mass per unit volume. Hence,
Density = Mass / Volume

Let’s learn these SAT math topics of Passport to Advance Math, one by one.
Exponents and Powers
An Exponent and Powers are ways to represent very large numbers or very small numbers in a simplified form.
For example, a very large number 1000000000000 (12 zeroes) can be simplified form as 10^{12}, where 12 is the exponent and 10 is the base. The whole expression 10^{12} is called as power.
Similarly, a very small number 0.000000000001 can be simplified as 10^{12} where 12 is the exponent and 10 is the base.
In exponents and powers of SAT Advance Math syllabus, you need to learn laws of exponents.
Laws of Exponents or Exponent Rules
For all integers m and n and any nonzero numbers a and b, the following properties exponent rules:
 Exponent Rules 1: a^{0} = 1
 For example: (2xy)^{0} = 1
 Exponent Rules 2: a^{1} = a
 For example: 10^{1} = 10
 Exponent Rules 3: a^{m} × a^{n }= a^{m + n}
 For example: 2^{5} × 2^{4 }= 2^{5 + 4} = 512
 Exponent Rules 4: a^{m} ÷ a^{n }= a^{m – n}
 For example: 2^{5} ÷ 2^{4 }= 2^{5 – 4} = 2
 Exponent Rules 5: (a^{m})^{n }= a^{mn}
 For example: (2^{5})^{4 }= 2^{5 × 4} = 2^{20}
 Exponent Rules 6: a^{m} × b^{m }= (ab)^{m}
 For example: 2^{5} × 3^{5 }= 10^{5} = 100000
 Exponent Rules 7: (a / b)^{m} = a^{m} / b^{m}
 For example: (2 / 3)^{5} = 2^{5 }/ 3^{5 }= 32 / 243
 Exponent Rules 8: a^{n} = 1 / a^{n}
 For example: 2^{2} = 1^{ }/ 2^{2 }= 1 / 4
 Exponent Rules 9: (a / b)^{n} = (b / a)^{n }= b^{n} / a^{n}
 For example: (2 / 3)^{2} = (3 / 2)^{2 }= 3^{2 }/ 2^{2 }= 9 / 4
Important Formulas for SAT : Polynomials
An algebraic expression p(x) of the form of p(x) = a_{n}x^{n} + a_{n1}x^{n1} + a_{n2}x^{n2} + … + a_{2}x^{2} + a_{1}x + a_{0}, where a_{0}, a_{1}, a_{2}, …, a_{n} are real numbers and n is a nonnegative integers.
Polynomials that have only one term are called monomials (Ex: 3x, 5x 3x/2, etc.).
Polynomials that have two unlike terms are called binomials (Ex: 3x + 6, 6x – 9y, 7y + 6 etc.).
Polynomials that have three unlike terms are called trinomials (Ex: 3x + 5y + 9, 9a – 6b + 5c etc.).
Terms such as 3x^{2} and −2x^{2} are called like terms because they have the same variable to the same power.
In polynomials of SAT Advance Math syllabus, you need to learn addition, subtraction, multiplication and division of polynomials, factorization of polynomials, LCM and HCF of polynomials, remainder theorem and factor theorem.
Addition of Polynomials
To add two or more polynomials, you need to add the coefficient of like terms.
For example:
(5x^{2} + 3x + 9) + (8x^{3} + 7x^{2} – 9x – 7) = 8x^{3} + (5 + 7)x^{2} + (3 – 9)x + (9 – 7) = 8x^{3} + 12x^{2} – 6x + 2
Subtraction of Polynomials
To subtract a polynomial from other, you need to subtract the coefficient of like terms.
For example:
(8x^{3} + 7x^{2} – 9x – 7) – (5x^{2} + 3x + 9) = 8x^{3} + (7 – 5)x^{2} + ( 9 – 3)x + ( 7 – 9) = 8x^{3} + 2x^{2} – 12x – 16
Multiplication or Product of Polynomials
To multiply two or more polynomials, you need to use the distributive property of multiplication over addition or subtraction and you need to use some laws of exponents.
For example:
8x^{3}(5x^{2} + 3x + 9) = (8x^{3} × 5x^{2}) + (8x^{3} × 3x) + (8x^{3} × 9) = 40x^{5} + 24x^{4} + 72x^{3}
Special Product of Polynomials
To find the special product of polynomials, you need to use following algebraic identities.
 (a + b)^{2} = a^{2} + 2ab + b^{2}
 (a – b)^{2} = a^{2} – 2ab + b^{2}
 (a + b)(a – b) = a^{2} – b^{2}
 (a + b + c)^{2} = a^{2} + b^{2} + c^{2} + 2ab + 2bc + 2ca
 (a + b)^{3} = a^{3} + b^{3} + 3ab(a + b)
 (a – b)^{3} = a^{3} – b^{3} – 3ab(a – b)
For example:
(8x + 3y)^{2 }= (8x)^{2} + 2(8x)(3y) + (3y)^{2} = 64x^{2} + 48xy + 9y^{2}
SAT Given Formulas : Division of Polynomials
To divide a polynomial by a monomial, divide each term by the monomial, add the results, and simplify.
For example:
Simplify (5x^{2} + 3x + 9) ÷ 2x
To divide a polynomial function f(x) by (ax + b) , you need to use long division, which is similar to long division in arithmetic, can be used to find quotient q(x) and remainder R.
For example: Divide (x^{3} + 2x^{2} – 5x + 9) ÷ (x – 2)
Factorization of Polynomials
A monomial is in factored form when it is expressed as the product of prime numbers and variables, and no variables has an exponent greater than 1.
For example: 102a^{2}b^{4} = 2 × 3 × 17 × a × a × b × b × b × b.
To factor a polynomial, always look first for GCD (Greatest Common Factor) of all the terms. If there is a GCF, factor it first.
For example: x^{4} + x^{3} – x^{2} = x^{2}(x^{2} + x – 1)
LCM and HCF of Polynomials
The HCF (Highest Common Factor) of two or more polynomials is the greatest polynomial that is a factor of each polynomial.
To find the HCF of two or more polynomial, take the smallest power of each prime factor and multiply.
The LCM (Least Common Multiple) of two or more polynomials is the least polynomials that is a common multiple of two or more polynomials.
To find the LCM of two or more polynomials, take the largest power of each prime factor and multiply.
For example:
Find the HCF and LCM of (x – y)^{2}(x + y) and (x – y)(x + y)^{3}.
(x – y)^{2}(x + y) = (x – y) × (x – y) × (x + y)
(x – y)(x + y)^{3} = (x – y) × (x + y) × (x + y) × (x + y)
HCF = (x – y)(x + y)
LCM = (x – y)^{2}(x + y)^{3}
Remainder Theorem
Let ‘p(x)‘ be any polynomial of degree greater than or equal to one and a be any real number.
If a polynomial p(x) is divided by a linear polynomial (x – a), then the remainder is constant polynomial p(a) = r.
For example:
Find the remainder when the polynomial p(x) = 3x^{2} + 6x – 8 is divided by (x – 1).
Required remainder is P(1) = 3 + 6 – 8 = 1
Factor Theorem
Let ‘p(x)‘ be any polynomial of degree greater than or equal to one and a be any real number such that p(a) = 0, then (x – a) is a factor of p(x).
For example:
Check whether (x – 1) is a factor of the polynomial p(x) = 3x^{2} + 5x – 8.
Since P(1) = 3 + 5 – 8 = 0, then (x – 1) is a factor of the polynomial p(x) = 3x^{2} + 5x – 8.
Quadratic Expressions and Equations
In quadratic expression and equations of SAT Advance Math topics, you need to learn about quadratic expressions or functions, quadratic equations, factorization of quadratic polynomials, solving quadratic equations, quadratic formulas, discriminant of quadratic equations, system of linear and quadratic equations, graph of quadratic polynomials and radical expressions etc.
Quadratic Expression or Function
A polynomial of the form of f(x) = ax^{2} + bx + c, where a ≠ 0, is known as quadratic polynomial or quadratic expression of quadratic function.
Quadratic Equation
An equation of the form of ax^{2} + bx + c = 0, where a ≠ 0, is known as quadratic equation.
The solutions of a quadratic function are the values of x for which f(x) = ax^{2} + bx + c. Solutions of functions are also called roots or zeros of the function.
Factorization of Quadratic Polynomials
A quadratic polynomial of the form of x^{2} + bx + c can be factorized as below.
If x^{2} + bx + c = x^{2} + (m + n)x + mn, where b = m + n and c = mn, then its factor form is x^{2} + bx + c = (x + m)(x + n).
For example: x^{2} + 5x + 6 = x^{2} + (3 + 2)x + (3 × 2) = (x + 3)(x + 2)
A quadratic polynomial of the form of ax^{2} + bx + c can be factorized as below.
If ax^{2} + bx + c = pqx^{2} + (ps + qr)x + rs, where a = pq, b = ps + qr and c = rs, then its factor form is ax^{2} + bx + c = (px + r)(qx + s).
For example: 5x^{2} + x – 4 = (5 × 1)x^{2} + (5 × 1 + 1 × 4)x + (4 × 1) = (5x – 4)(x + 1)
Solving Quadratic Equations
To solve a quadratic equation p(x) = ax^{2} + bx + c = 0, you need to use factorization of the quadratic function or use a quadratic formula.
Solving Quadratic Equations by Factorization
If the product a b⋅ = 0 , then either a = 0 , b = 0 , or both a and b equal zero. Factoring and zero product property allow you to solve a quadratic equation by converting it into two linear equations.
To solve a quadratic equation p(x) = ax^{2} + bx + c = 0 by factorization, first you need to factorize the quadratic function and then equate each factor as zero and then find the values of x.
For example:
Solve 5x^{2} – 14x – 3 = 0.
⇒ 5x^{2} – 15x + x – 3 = 0
⇒ 5x(x – 3) + 1(x – 3) = 0
⇒ (5x + 1)(x – 3) = 0
⇒ (5x + 1) = 0 or (x – 3) = 0
⇒ x = 1/5 or x = 3
SAT Formulas : Quadratic Formula
If ax^{2} + bx + c = 0, where a ≠ 0, then the formula to find the values of x is known as quadratic formula, which is
Discriminant of Quadratic Equations
In a quadratic formula, the expression under the radical sign (b^{2} – 4ac) is called the discriminant of the quadratic equation.
The value of the discriminant can be used to determine the number of real roots for the quadratic equation.
Solving Quadratic Equations by Quadratic Formula
To solve a quadratic equation p(x) = ax^{2} + bx + c = 0 by quadratic formula, you need to use the quadratic formula.
For example:
Solve 2x^{2} – 4x – 3 = 0.
Graph of Quadratic Polynomial
The graph of a quadratic polynomial y = p(x) = ax^{2} + bx + c, is a parabola. The parabola can be upward or downward, it depends on the sign of ‘a‘ (coefficient of x^{2}).
If a > 0 , the graph opens upward and the vertex is the minimum point.
If a < 0 , the graph opens downward and the vertex is the maximum point.
The maximum or minimum point of a parabola is called the vertex, whose the coordinate of the vertex is V(b/2a, D/4a).
In this case, the maximum and minimum values of the quadratic polynomial is as below.
In this case, the maximum and minimum values of the quadratic polynomial is as below.
Solving Systems Consisting Linear and Quadratic Equations
A system containing only quadratic equations or a combination of linear and quadratic equations in the same two variables is called a quadratic system.
The substitution and elimination methods used to solve linear systems can also be used to solve quadratic systems algebraically.
You can use graphs to find the number of real solutions of a quadratic system.
If the graphs of a system of equations are a quadratic and a linear, the system will have 0, 1, or 2 solutions.
If the graphs of a system of equations are two quadratic equations, the system will have 0, 1, 2, 3, or 4 solutions.
Radical Expressions and Equations
In radicals expression and equations of SAT Advance Math topics, you need to learn about radicals and how to solve the equations containing radicals.
SAT Formula Sheet : Radicals
For any real numbers x or a, and any positive integer n , if x^{n} = a, then x is an nth root of a, it means x = .
The symbol is called a radical.
The term is also written as (a)^{1/n}.
Product and Quotient Property of Radicals
Solving Radicals Equations
An equation which contains a radical with a variable in the radicand is called a radical equation. To solve such an equation, first isolate the radical on one side of the equation. Then square each side of the equation to eliminate the radical.
For example:
SAT Math Checklist : Trigonometry
In trigonometry of SAT Advance Math topics, you need to learn about degree and radian measurement of angles, basic definition of trigonometric ratios, trigonometric values, trigonometric identities, trigonometric values of complementary angles etc.
Degree and Radians Measurement of Angles
One radian is the measure of a central angle θ whose intercepted arc has a length equal to the circle’s radius.
In the figure below, if length of the arc AB = OB = OA = r, then m ∠AOB = 1 radian.
To convert an angle in degree into radian, we need to multiply π/180 to the degree.
For example: 30 degree = 30 x π/180 = π/6 radian.
To convert an angle in radian into degree, we need to multiply 180/π to the degree.
For example: π/6 radian = π/6 x 180/π = 30 degree.
Trigonometric Ratios of Acute Angles
In trigonometry, we study the relation between the sides and angles of a right triangle. For this, six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent (their abbreviations are sin, cos, tan, csc, sec, and cot, respectively) are defined as below.
Trigonometric Quotient Identities
tanθ = sinθ / cosθ and cotθ = cosθ / sinθ
Trigonometric Reciprocal Identities
sinθ × cosecθ = 1 or sinθ = 1/ cosecθ and cosecθ = 1/ sinθ.
cosθ × secθ = 1 or cosθ = 1/ secθ and secθ = 1/ cosθ.
tanθ × cotθ = 1 or tanθ = 1/ cotθ and cotθ = 1/ tanθ.
Trigonometric Identities
sin^{2}θ + cos^{2}θ = 1
sec^{2}θ – tan^{2}θ = 1
cosec^{2}θ – cot^{2}θ = 1
Trigonometric Values
There are some specific trigonometric values of certain angles which are given below in trigonometric table.
Trigonometric Values of Complementary Angles
sin(90^{o} – θ) = cosθ
cos(90^{o} – θ) = sinθ
tan(90^{o} – θ) = cotθ
cosec(90^{o} – θ) = secθ
sec(90^{o} – θ) = cosecθ
cot(90^{o} – θ) = tanθ

In a triangle, an exterior angle is the sum of the measures of the two opposite interior angles.
In triangle ABC, m∠BCD = m∠A + m∠B.
Pythagoras Theorem of Triangle
According to Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the legs equals the square of the length of the hypotenuse.
Congruent Triangles
Two triangles are said to be congruent, if the triangles are same shape and same size. And, the same shape is identified by their angles and same size is identified by their sides.
Thus, the triangles whose corresponding angles are equal and corresponding sides are equal, then the triangles are congruent.
Similar Triangles
Two triangles are said to be similar, if the triangles are same shape and proportional size. And, the same shape is identified by their angles and same size is identified by their sides.
Thus, the triangles whose corresponding angles are equal and corresponding sides are proportional, then the triangles are similar.
Triangle Proportionality Theorem
If a line parallel to one side of a triangle intersects the other two sides, it divides those sides proportionally.
If D and E are the midpoints of AB and BC , AC  DE, then DE = AC / 2.
Angle Bisector Theorem
An angle bisector of a triangle splits the opposite side into the segment that have same ratio of the lengths as the sides adjacent to angle.

Circles
In Circles of SAT Geometry Topics, you need to learn about basic definition of terms related to circles like chords, tangents, secants, central angle, sectors, segments, and how to find arc lengths, and some theorems of circles, and equations of circles.
What is a Circles?
A circle is a locus of a point which moves such that its distance from a fixed point is always constant. The fixed point is known as center of the circle and the constant distance is known as radius of circle. The moving point traced the circumference of circle. OR, you can also define as a circle is the set of all points equidistant from a given point called the center. It follows from the definition of a circle that all radii are equal in measure.
Basic Terms Related to Circles
A chord is a segment whose endpoints lie on a circle.
A secant is a line that contains a chord.
A tangent is a line in the plane of a circle, and intersects the circle at exactly one point: the point of tangency.
A central angle is an angle whose vertex is the center of the circle.
An arc is a part of a circle.
The measure of a minor arc is the measure of its central angle. The measure of a minor arc is less than 180.
