What is the Policy on Using a Calculator on the Math GRE?

The Educational Testing Service (ETS), which administers the GRE, has a clear policy: an on-screen calculator is provided for the Quantitative Reasoning sections of the computer-delivered test. For the paper-delivered test, a similar handheld calculator is provided by the test center. You are strictly prohibited from bringing your own calculator, be it physical or an app on a watch. This rule ensures fairness and focuses the test on logical reasoning rather than complex computation. The availability of the calculator is a key part of test strategy, and knowing how and when to use this tool is crucial for anyone aiming for a high score. Many test-takers find that practicing with a GRE score calculator can help them set realistic targets.

The GRE Calculator’s Formula and Explanation

The GRE calculator is a basic four-function tool with a few extras. It is not a scientific calculator. Its primary purpose is to handle tedious arithmetic, allowing you to focus on the problem-solving aspects of the questions. The calculator correctly follows the standard order of operations (PEMDAS/BODMAS). For example, in an expression like 5 + 2 * 3, it will calculate 2 * 3 first, then add 5, yielding 11.

The table shows the functions of the on-screen GRE calculator. The display is limited to 8 digits.

Function	Button	Meaning	Unit	Typical Range
Arithmetic	+, -, ×, ÷	Performs basic addition, subtraction, multiplication, and division.	Unitless	Up to 8 digits
Square Root	√	Calculates the square root of the displayed number.	Unitless	Non-negative numbers
Memory Store	M+	Adds the current display value to the number in memory.	Unitless	Any number
Memory Recall	MR	Recalls the number stored in memory to the display.	Unitless	N/A
Memory Clear	MC	Clears the number stored in memory (resets to zero).	Unitless	N/A
Clear All	C	Clears all current calculations and the display.	Unitless	N/A

Practical Examples

Example 1: Multi-Step Arithmetic

A question asks for the total cost of 15 items at $3.80 each, after a 5% processing fee on the total.

Inputs:

1. Calculate subtotal: 15 * 3.80 = 57

2. Calculate fee: 57 * 0.05 = 2.85

3. Calculate total: 57 + 2.85 = 59.85

Result: $59.85. The calculator is perfect for avoiding small errors in multiplication and addition.

Example 2: Using the Square Root

You need to find the length of the diagonal of a rectangular room with sides of 7 meters and 12 meters. Using the Pythagorean theorem (a² + b² = c²).

Inputs:

1. Calculate a²: 7 * 7 = 49

2. Calculate b²: 12 * 12 = 144

3. Calculate a² + b²: 49 + 144 = 193

4. Find the diagonal (c): √193 ≈ 13.89

Result: Approximately 13.89 meters. This is a prime example of where the calculator saves significant time over manual estimation.

How to Use This can you use a calculator on the math gre Calculator

Our simulator is designed to mirror the functionality of the actual GRE on-screen calculator. Here’s how to use it effectively for your GRE quant preparation:

1. Policy Check: Use the dropdown menu to select a GRE section. The result box will confirm whether a calculator is provided for that section, matching the official test rules.
2. Enter Numbers: Click the number buttons (0-9) to form your input.
3. Perform Calculations: Use the operator buttons (+, -, ×, ÷) to perform calculations. The simulator follows the correct order of operations.
4. Use Advanced Functions: Practice with the square root (√) and memory (M+, MR, MC) functions, as these are common sources of confusion on test day.
5. Interpret Results: The result is shown in the display. The ‘C’ button clears the current entry and calculation.

Key Factors That Affect Your Calculator Strategy

• Time Management: The calculator can be slow to use with a mouse. For simple calculations like 10 * 5, mental math is much faster. Reserve the calculator for tedious multi-digit arithmetic.
• Problem Complexity: The GRE is a reasoning test. If a problem seems to require a very complex calculation, you might be missing a logical shortcut. Don’t let the calculator become a crutch.
• Knowing When NOT to Use It: For questions involving fractions or variables, the calculator is often useless. Your conceptual knowledge is what’s being tested.
• Familiarity with the Interface: Practice using the on-screen calculator during your prep. Knowing exactly how the memory and order of operations functions work will prevent costly mistakes. This is a core component of mastering GRE test day rules.
• Estimation Skills: Before using the calculator, estimate the answer. This helps you quickly spot a potential typo or error if the calculated result is wildly different from your estimate.
• No Advanced Functions: Remember, there are no exponents, logarithms, or trigonometric functions. Problems requiring these concepts will always have a simpler, logic-based solution path.

Frequently Asked Questions (FAQ)

1. Can I bring my own calculator to the GRE?

No, personal calculators are strictly forbidden in both the test center and for the at-home GRE test. You must use the provided on-screen calculator.

2. Is the GRE calculator scientific?

No, it is a basic, four-function calculator with square root and memory functions. It does not have the capabilities of a scientific or graphing calculator.

3. Does the calculator follow the order of operations (PEMDAS)?

Yes, the on-screen calculator for the computer-based GRE correctly follows the order of operations. For example, multiplication is performed before addition.

4. What are the main limitations of the GRE calculator?

The primary limitations are an 8-digit display, no exponent or root functions beyond square root, and no ability to handle fractions or complex scientific notations.

5. Should I use the calculator on every quant question?

No, this is a poor strategy. Many questions are designed to be solved faster with mental math or logical reasoning. Over-reliance on the calculator can waste significant time. Some good GRE calculator tricks involve knowing when to put it away.

6. How do the memory functions (M+, MR, MC) work?

M+ adds the current number on the display to the value in memory. MR recalls the memory value to the display. MC clears the memory, resetting it to zero. These are useful for multi-step calculations.

7. Is there a calculator for the Verbal or Writing sections?

No, the calculator is only available during the Quantitative Reasoning sections of the GRE.

8. What is the ‘Transfer Display’ button?

For Numeric Entry questions, this button allows you to transfer the number from the calculator’s display directly into the answer box, reducing the chance of a typo.
