Giving emphasis to GRE geometry can be helpful in exam prep. Practice recognizing when a problem involves a triangle to save time and boost accuracy.- Calculating
**percent**is a frequent task in the**math section**. Whether you’re working with interest rates, population growth, or discounts, understanding how to manipulate percentages will make these questions straightforward. Memorize common percent formulas to avoid mistakes on test day. - Problems involving
**integers**,**ratios**, and**fractions**are common in the**quant section**. You may need to manipulate these numbers in a variety of ways, often using them to find relationships between quantities. Practice these concepts through**practice question**sets to get a solid handle on them. Make sure you have a clear idea of the difference between the GRE general test and the subject test as well. - Be ready to interpret data using
**graphs**and charts, a recurring feature in the**GRE quantitative reasoning**section. Understanding how to extract information from bar graphs, pie charts, and scatter plots is key to answering data-driven questions. Watch for tricky**answer choice**traps. - Basic algebraic operations involving
**exponents**,**decimals**, and**standard deviation**frequently show up in the**GRE quantitative**section. You don’t need to know advanced**calculus**, but knowing how to work with these values can make solving problems faster. Review key formulas to**solve the problem**efficiently. - Geometry questions about
**quadrilaterals**, circles, and other shapes are standard on the**GRE test**. These problems often involve using formulas for area, perimeter, and sometimes angles.**ETS**loves to test your ability to recall these formulas quickly and apply them to both simple and complex figures.

## GRE Math Cheat Sheet: The Important GRE Math Formulas You Must Know

When preparing for the GRE, having a solid grasp of key math formulas is essential. Keeping in mind the GRE exam dates, make sure your preparation plan aligns with it. Below is a cheat sheet of the most important **GRE math** formulas you’ll need to **memorize** for the **quantitative reasoning section**:

**Area of a Triangle**: Multiply one-half by the base of the triangle, then multiply by the height.**Pythagorean Theorem**(for right triangles): The square of the hypotenuse (the longest side) equals the sum of the squares of the other two sides.**Area of a Circle**: Multiply pi (approximately 3.14) by the square of the radius.**Circumference of a Circle**: Multiply two by pi, then multiply by the radius.**Slope of a Line**: Subtract the first y-coordinate from the second y-coordinate, then divide by the difference between the corresponding x-coordinates.**Quadratic Formula**: For any quadratic equation in the form of ax² + bx + c, the solutions are given by: negative b, plus or minus the square root of b-squared minus 4ac, divided by 2a.**Percentage Formula**: To find a percentage, divide the part by the whole, then multiply by 100.**Simple Interest**: Multiply the principal amount by the interest rate and the time (usually in years).**Distance Formula**(between two points): Find the difference between the x-coordinates and y-coordinates of two points, square each difference, then add them and take the square root.**Standard Deviation**: Subtract the mean from each data value, square the result, find the average of those squares, and then take the square root.

These formulas will help you tackle the most common questions in the **GRE math section**, whether you’re dealing with geometry, algebra, or data interpretation. Understanding the benefits of the GRE exam helps you prepare even more effectively.

## Why Should You Memorize Math Formulas?

Memorizing important GRE math formulas is essential when preparing for the GRE exam, especially for the GRE quantitative section. On test day, you’ll need to recall formulas for areas like simple and compound interest, probability of an event, and even the area formula for a rectangle to solve the math involved quickly. Since you’ll be tested on the GRE in various areas of math, such as algebra and geometry, knowing these formulas by heart will save valuable time and help you perform well in the GRE math section.

When you’re taking practice tests or working through an official practice book, using the math formulas you need will give you a better understanding of how to approach each problem. You’ll be tested on how well you can compare quantities using ratios or interpret data presented in tables, and knowing the important formulas can help you verify your answers.

Memorizing these formulas will also give you an edge in solving the GRE math concepts that often appear in the quantitative reasoning section, ultimately boosting your quant score and helping you get into grad school. Have a clear idea of the GRE cut-off to gain an idea of where you have to work towards. Make sure you understand these formulas and put them to use during your GRE math practice—it will pay off on the actual GRE.
