Understanding the GRE Math Section
Before we dive into the formulas, it’s important to understand what to expect from the GRE math section. The GRE math section, also known as the Quantitative Reasoning section, consists of two parts:
-
Quantitative Comparison (QC): You'll be given two quantities and asked to determine their relationship (greater, less, or equal).
-
Problem-Solving: These questions include a mix of algebra, arithmetic, geometry, and data analysis.
The key to doing well on this section is familiarity with the math concepts and formulas that frequently appear in these questions. Knowing these formulas will help you work more efficiently and solve problems more quickly, giving you the confidence you need to ace the test.
Must-Know GRE Math Formulas
-
-
Linear Equation:
y=mx+by = mx + b
This is the equation of a straight line, where mm is the slope, and bb is the y-intercept. -
Quadratic Formula:
x=−b±b2−4ac2ax = \frac{-b \pm \sqrt{b^2 – 4ac}}{2a}
Use this formula to solve quadratic equations of the form ax2+bx+c=0ax^2 + bx + c = 0.

Percentages:
Percentage=PartWhole×100\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100 -
Average (Mean):
Average=Sum of ValuesNumber of Values\text{Average} = \frac{\text{Sum of Values}}{\text{Number of Values}} -
Simple Interest:
I=P×r×tI = P \times r \times t
Where II is the interest, PP is the principal amount, rr is the rate, and tt is the time.

-
Area of a Triangle:
A=12×Base×HeightA = \frac{1}{2} \times \text{Base} \times \text{Height} -
Area of a Circle:
A=πr2A = \pi r^2
Where rr is the radius of the circle. -
Perimeter of a Rectangle:
P=2×(Length+Width)P = 2 \times (\text{Length} + \text{Width}) -
Volume of a Rectangular Prism:
V=Length×Width×HeightV = \text{Length} \times \text{Width} \times \text{Height}

Data Analysis Formulas
-
Median:
The middle value of a data set when arranged in ascending or descending order. -
Range:
Range=Maximum Value−Minimum Value\text{Range} = \text{Maximum Value} – \text{Minimum Value} -
Standard Deviation:
The formula for calculating standard deviation is a bit more complex, but in simple terms, it measures how spread out the numbers in a data set are from the mean.

-
Probability of an Event:
P(E)=Number of Favorable OutcomesTotal Number of OutcomesP(E) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Outcomes}}
