Can a Calculator Be Used on the GRE?
An interactive tool and detailed guide to understand the GRE’s on-screen calculator policy and strategy.
GRE Calculator Availability Overview
| GRE Section | Calculator Provided? | Type of Calculator |

| Verbal Reasoning | No | N/A |
| Analytical Writing (AWA) | No | N/A |
What is the GRE Calculator?
A common question for test-takers is: can a calculator be used on the GRE? The answer is yes, but with important limitations. You cannot bring your own calculator. Instead, the GRE provides a basic on-screen calculator exclusively for the Quantitative Reasoning sections. This tool is intended to help with tedious calculations, not to replace your mathematical reasoning skills. It is not available for the Verbal Reasoning or Analytical Writing sections.
Understanding when and how to use the GRE calculator is a critical part of test strategy. Over-reliance can waste precious time, while strategic use can speed up computations and improve accuracy. Many questions are designed to be solved more quickly through logic and estimation than with the calculator.
Common Misconceptions
- Misconception 1: You can bring your own scientific calculator. False. Personal calculators are strictly prohibited to ensure a level playing field. Only the provided on-screen calculator is allowed.
- Misconception 2: The calculator is available for the entire test. False. Access is limited to the Quantitative Reasoning sections only.
- Misconception 3: The calculator can solve complex problems for you. False. It’s a basic four-function calculator with a square root button. It tests arithmetic, not problem-solving. Your strategy for GRE math should not solely depend on it.
How the On-Screen Calculator Works
The question of whether a calculator can be used on the GRE comes with a need to understand the tool’s functions. The GRE calculator is basic, but it correctly follows the mathematical order of operations (PEMDAS/BODMAS). For example, if you input `3 + 5 * 2`, it will calculate `5 * 2` first, then add `3` for a correct result of `13`.
It includes memory functions (M+, MR, MC) and a “Transfer Display” button for numeric entry questions, which can save time by moving the result directly to the answer box. However, it has limitations, such as an 8-digit display and an inability to handle nested parentheses.
Calculator Functions Table
| Button/Function | Meaning | Typical Use |
|---|---|---|
| +, -, *, / | Basic Arithmetic | Addition, Subtraction, Multiplication, Division. |
| √ (sqrt) | Square Root | Finding the square root of a number. |
| ( ) | Parentheses | Grouping operations (nesting is not supported). |
| M+ | Memory Plus | Adds the current display value to the value in memory. |
| MR | Memory Recall | Recalls the value stored in memory to the display. |
| MC | Memory Clear | Clears any value stored in memory. |
| Transfer Display | Copy to Answer | For numeric entry questions, pastes the result into the answer box. |
Practical Examples of Using the GRE Calculator
Knowing a calculator can be used on the GRE is only half the battle. You must know *when* to use it. It’s for computation, not for strategy. Explore different GRE quant tips to build a solid strategy.
Example 1: When the Calculator is Useful
Question: A store buys a batch of 150 widgets for $198.75. If it sells each widget for $2.50, what is the total profit for the batch?
- Step 1 (Calculator): Calculate total revenue. `150 * 2.50 = 375`.
- Step 2 (Calculator): Calculate profit. `375 – 198.75 = 176.25`.
- Interpretation: The total profit is $176.25. The calculator is perfect here for avoiding manual errors with decimals and multiplication.
Example 2: When the Calculator is a Trap
Question: Which is greater, 9³¹ or 3⁶⁰?
- Wrong Approach (Calculator): Trying to calculate 9³¹ or 3⁶⁰ will result in an error, as the numbers are too large for the 8-digit display. This shows the limits of using a calculator on the GRE.
- Right Approach (Logic): Use number properties. Rewrite 9³¹ as (3²)³¹, which equals 3⁶². Since 3⁶² is greater than 3⁶⁰, 9³¹ is the larger value.
- Interpretation: This problem tests your knowledge of exponents, not your ability to compute large numbers. Relying on the calculator would be a time-wasting trap.
How to Use This Calculator and the Official GRE Calculator
Using This Page’s Tool
- Select the Section: Choose the GRE section (Quantitative, Verbal, AWA) from the dropdown menu.
- View the Result: The tool will instantly tell you if a calculator is available and provide key details.
- Explore: Use the result to understand the specific rules for that section of the test.
Using the Official GRE On-Screen Calculator
- Problem Solve First: Always analyze the problem first. Decide on a logical path to the solution before touching the calculator.
- Use for Tedious Arithmetic: The calculator is your friend for multi-digit multiplication, long division, or calculations with decimals and square roots.
- Don’t Use for Simple Math: Simple calculations like `15 * 10` or `50 / 2` are faster to do mentally.
- Practice Before Test Day: Familiarize yourself with the on-screen calculator’s interface and functions using official ETS practice materials to improve your GRE scoring potential.
Key Factors That Affect Performance with the GRE Calculator
Successfully navigating the question “can a calculator be used on the GRE” depends on several strategic factors.
- Time Management: Using the on-screen calculator with a mouse can be slower than mental math. Only use it when it saves time, not costs it.
- Over-Reliance: The biggest pitfall is trying to use the calculator for every problem. Many questions are designed to test logic and can be solved faster without it.
- Knowing When to Estimate: Sometimes, a rough estimation is enough to eliminate wrong answer choices, which is much faster than a precise calculation.
- Familiarity with the Interface: Practice with the official GRE POWERPREP tests to get used to the calculator’s layout, including its memory and transfer functions. Understanding the Verbal Reasoning strategies is just as important as math practice.
- Avoiding Input Errors: Carefully check the numbers you type into the calculator. A single mistyped digit can lead to a wrong answer.
- Number Properties Knowledge: Strong knowledge of topics like divisibility, exponents, and patterns will help you identify when a problem is testing logic rather than arithmetic, allowing you to bypass the calculator entirely.
Frequently Asked Questions (FAQ)
No, the on-screen calculator is only provided for the Quantitative Reasoning sections. It is not available during the Verbal Reasoning or Analytical Writing section.
No, personal calculators of any kind are strictly forbidden. You must use the on-screen calculator provided by ETS.
No, it is a basic calculator. It can perform addition, subtraction, multiplication, division, and square roots. It also has parentheses and memory functions but lacks advanced scientific or graphing capabilities.
Yes, the GRE calculator correctly follows the order of operations. For instance, it will perform multiplication before addition.
No. This is a common mistake. Many questions are designed to be solved faster with mental math, estimation, or logical reasoning. The best approach to answer if a calculator can be used on the GRE effectively is to use it strategically.
The calculator only has an 8-digit display. If a number is too large, it will result in an error. This is a strong hint that you should solve the problem using number properties or logic instead of brute-force calculation.
M+ adds the current number to memory, MR recalls the memory value, and MC clears the memory. Be careful: M+ adds to the existing memory, it doesn’t replace it.
Yes, the on-screen calculator provided is identical whether you take the test at home or at a designated test center.
