Key Takeaways
- GRE calculator helps reduce silly mistakes under time pressure, boosting accuracy in the quant section.
- Best used for decimals, square roots, and multi-step problems, while mental math is faster for simple arithmetic.
- Practicing with it during full-length tests builds confidence and improves your overall quant score.
Almost 90% of all test-takers report that time pressure in the GRE Quant section results in silly mistakes, even a simple problem with arithmetic or a square root. Most of the time, the problems weren’t very difficult for Indian students, but time pressure makes even whole number multiplication or placing the decimal in the right spot hard!
The best advantage is that you have access to the GRE calculator during the test. By learning how to use the GRE calculator intelligently, you can increase typing accuracy, save time, and save your GRE score.
What is the GRE on-screen calculator?
The GRE on-screen calculator is a simple, built-in tool provided during the GRE test for the quantitative section. Unlike a physical calculator, you cannot bring your own due to ETS’s strict calculator policy. Instead, the exam software provides a real GRE calculator on your screen. You’ll need to use the mouse to click numbers or type them in.
This simple on-screen calculator can handle basic GRE arithmetic, fractions, decimal points, square root function, negative numbers, and memory buttons. It’s designed for simple calculations that help avoid silly mistakes, not for solving complex math problems.
While a physical calculator vs. on-screen calculator feels different, practicing with tools like PowerPrep or an online GRE calculator helps you get a feel for the display and become familiar before test day. Using the GRE calculator wisely ensures better speed and accuracy and a good GRE score.
Why Students Should Use the Calculator during Test Prep?
During GRE prep, students often focus only on mental math or flashcards, but the reality is that the GRE calculator is available in the quantitative section of the GRE exam.
Practicing with it during practice tests helps you get used to the calculator display, memory function, and shortcuts like handling parentheses or decimals.
By learning when to use a calculator to solve simple arithmetic and when to avoid it, you sharpen speed and accuracy, ultimately improving your GRE quant score.
What are the Features of the GRE Calculator?
The GRE calculator is a simple on-screen tool provided by ETS during the GRE quantitative section.

While it cannot replace strong math skills, practicing with it helps you avoid silly mistakes and manage time better. Knowing its features ensures you use it wisely in the real exam.
