Important GRE Math Formulas

The Quantitative Reasoning section is just one of three parts of the GRE. In this section, students must answer algebra, arithmetic, geometry, and data analysis questions. In order to prep for this section of the test, students must take time to learn some GRE math formulas, as these formulas aren’t provided on the test. Check out some examples of math formulas for GRE questions and get some tips on how to master this section of the exam.

Examples of GRE Math Formulas

  • Slope-intercept: y = mx + b
  • Distance = Rate * Time or D = RT
  • Average Speed = Total Distance/Total Time
  • For squares: Perimeter = 4s (side); Area = s2
  • For rectangles: Area = Length * Width or A= lw; Perimeter= 2l + 2w
  • For polygons: Total degrees = 180(n-2), where n = the number of sides
  • For circles: Area = πr2 , Circumference = 2πr

Tips for the Quantitative Section
As a student works through this portion of the test, it’s helpful to scan through the answer options and eliminate those that are clearly incorrect. Crossing out these options helps to make a math problem more manageable for a student. Plus, the student doesn’t have to waste time considering answer options that are definitely not going to work.

A second tip is to work problems out on scrap paper. This is especially beneficial when working on word problems – a student is able to see all of the parts of a problem without having to mentally juggle a lot of figures. Furthermore, if a student arrives at an answer that doesn’t match up with any of the options, they can go back to the work on the scrap paper to find the mistake.

Students may want to get into the habit of estimating the answer before considering any of the answer options. This gives the student a rough idea of what the answer looks like before choosing the official solution from the multiple options.

In order to save test time, it’s also a good idea for students to skip extremely puzzling questions and return to them later on in the test period. A student who spends too much time on one problem in the quantitative reasoning section is likely to run out of time before finishing the rest of the section. Students who take the computer-delivered version of the GRE are able to use a convenient “mark and review” tool that helps them to remember the questions that were skipped and go back to them.

Studying for the Quantitative Section
Memorizing math formulas for GRE questions is just one of the effective ways to study for the GRE. Working on practice math problems is another way to prep for the test. This gives a student the opportunity to practice using those math formulas. As they work through a variety of problems, students can become familiar with when to use a particular GRE math formula.

Some students find it helpful to make flash cards with math formulas on them. They can quiz themselves by holding up a flash card with a GRE math formula on it. Next, the student should successfully complete a problem using that formula.

Online math games are another study tool used by many students. Games can be a fun way for students to refresh their algebra skills or get reacquainted with the rules of geometry. Some students like to pair with another person to play these types of math games. Competing with a friend to see who can score more points and end up with more correct answers can be motivating to many students who plan to take the GRE. Plus, it’s always helpful to hear encouraging words from a friend.
