The Official Policy on Using a Calculator on the GRE
One of the most frequent questions from test-takers is “can I use a calculator on the GRE?“. The answer is yes, but with critical limitations. You cannot bring your own calculator. Instead, a basic on-screen calculator is provided, but only for the Quantitative Reasoning sections. Understanding when and how to use this tool is a key part of an effective GRE preparation strategy. For many, relying on mental math is faster and more efficient than using the clunky on-screen tool for simple calculations.
What is the GRE Calculator Policy?
The official policy from ETS (Educational Testing Service) is straightforward: a calculator is available only during the Quantitative Reasoning sections of the GRE General Test. You are strictly prohibited from using a personal calculator, a calculator on your phone, or any other external device. This policy ensures a level playing field for all test-takers. The question of if you can use a calculator on the GRE is therefore a “yes” for the math sections and a firm “no” for the Verbal and Analytical Writing sections.
A common misconception is that the calculator is a powerful tool. In reality, it’s a very basic four-function calculator with square root and memory functions. Over-reliance on it can waste valuable time. The fact that you can use a calculator on the GRE doesn’t mean you always should.
GRE Calculator Functionality Explained
The on-screen calculator is designed to handle tedious arithmetic, not to solve problems for you. Its functionality is limited. The debate over whether you can use a calculator on the GRE should also include how it works. It follows the standard order of operations (PEMDAS), which is an important detail. For example, `2 + 3 * 4` will correctly result in 14, not 20. Here is a breakdown of its functions.
| Function | Symbol/Button | Meaning | Typical Use |
|---|---|---|---|
| Addition | + | Sums two numbers | Simple arithmetic |
| Subtraction | – | Finds the difference | Simple arithmetic |
| Multiplication | * | Multiplies two numbers | Complex arithmetic |
| Division | / | Divides two numbers | Finding ratios, rates |
| Square Root | sqrt | Finds the square root | Geometry problems |
| Memory (M+, MR, MC) | M+, MR, MC | Store, recall, or clear a number | Multi-step calculations |
Practical Examples of Calculator Use
Knowing you can use a calculator on the GRE is one thing; knowing when is another. Here are two real-world scenarios.
Example 1: When to Use the Calculator
Problem: A purchase of $154.65 is discounted by 35%. What is the final price?
Interpretation: This involves messy decimals, making it a perfect candidate for the calculator. You would first calculate the discount amount: `154.65 * 0.35 = 54.1275`. Then, find the final price: `154.65 – 54.1275 = 100.5225`. The answer is approximately $100.52. Here, the query “can I use a calculator on the GRE” is answered with a strategic ‘yes’.
Example 2: When NOT to Use the Calculator
Problem: Which is greater, 88 * 92 or 80 * 100?
Interpretation: Reaching for the calculator is a trap. This problem tests number sense. You can recognize that 88 * 92 is the same as (90 – 2) * (90 + 2), which simplifies to 90² – 2² = 8100 – 4 = 8096. The second product, 80 * 100, is 8000. Clearly, 8096 is greater. Mental math is far quicker and demonstrates a deeper understanding than blindly using the calculator.
How to Use This GRE Calculator Policy Checker
This tool is designed to give you a quick and accurate answer regarding the GRE calculator rules.
- Select the Section: Use the dropdown menu to choose the GRE section you are interested in (Quantitative Reasoning, Verbal Reasoning, or Analytical Writing).
- View the Result: The main result box will immediately update to “YES” or “NO” with a corresponding color code. This instantly tells you if you can use a calculator on the GRE for that specific section.
- Review the Details: The intermediate values and the dynamic chart provide further context, confirming the section you selected, the permission status, and the type of calculator available (if any).
Key Factors That Affect Calculator Strategy
Your decision about whether to use the calculator should be strategic. Here are six factors to consider.
- Calculation Complexity: Only use the calculator for arithmetic that is too cumbersome for mental math (e.g., multi-digit multiplication, long division, square roots of non-perfect squares).
- Time Cost: Using the on-screen calculator with a mouse can be slow. Often, quick estimation or mental math is faster. Every second counts on the GRE.
- Question Type: Quantitative Comparison questions often rely on logic and number properties rather than complex calculation. Using a calculator on these can be a waste of time. Numeric Entry questions are more likely to require precise calculation.
- Mental Math Proficiency: The more comfortable you are with mental arithmetic and estimation, the less you’ll need the calculator. This is a skill that can be improved with practice.
- The “Calculator Trap”: Test makers often design problems that seem to require a calculator but have elegant, logical shortcuts. Falling for the trap demonstrates a lack of strategic thinking. The question isn’t just “can I use a calculator on the GRE,” but “should I?”
- Familiarity with the Tool: Practice with the official ETS PowerPrep tests to get used to the on-screen calculator’s interface and limitations. Don’t let test day be the first time you use it.
Frequently Asked Questions (FAQ)
No. You are strictly forbidden from bringing any personal calculators. You may only use the on-screen calculator provided during the Quantitative Reasoning sections.
No. The on-screen calculator is ONLY available during the two Quantitative Reasoning sections. It is not available for the Verbal Reasoning or Analytical Writing sections.
It is a basic calculator with addition, subtraction, multiplication, division, square root, and memory functions (M+, MR, MC). It does not have scientific or graphing functions.
Yes, the on-screen calculator is identical for both the at-home GRE and the version administered at a test center.
Yes. It correctly follows the mathematical order of operations, which is a key feature to be aware of. For example, it will perform multiplication before addition.
The best way is to use the free PowerPrep Online practice tests provided by ETS. They feature the exact same on-screen calculator you will see on test day. This is the best way to determine if you can use a calculator on the GRE effectively.
Using the number pad on your keyboard is significantly faster than clicking the numbers with a mouse. It is highly recommended to practice using the keyboard for input.
Absolutely not. In fact, most questions do not require it. Many problems are designed to test your reasoning and estimation skills, where using a calculator would actually slow you down. Knowing you can use a calculator on the GRE is only half the battle.
