What is the Calculator Allowed in GRE Tests?

The **calculator allowed in GRE** is a basic, on-screen digital tool provided during the Quantitative Reasoning sections of the exam. It is critical to understand that you are strictly prohibited from bringing your own physical calculator. The provided tool is designed to handle simple arithmetic, but it lacks the advanced functions of scientific or graphing calculators. Its purpose is to aid in tedious calculations, not to replace strong mathematical reasoning. Over-reliance on this tool can actually slow you down, so understanding its features and limitations is key to a successful GRE Quant performance.

Who Should Use It?

Every GRE test-taker should familiarize themselves with the calculator, but its use should be strategic. It’s most helpful for computations that are time-consuming or prone to manual error, such as multiplying multi-digit numbers, long division, or finding the square root of a non-perfect square. However, for many problems, mental math, estimation, or algebraic simplification is much faster. The most successful students are those who know when to use the calculator and when to rely on their GRE quant strategies.

Common Misconceptions

A primary misconception is that the calculator is a powerful tool that can solve any problem. In reality, the **calculator allowed in GRE** is intentionally basic. It does not have buttons for exponents, trigonometry, or complex order of operations with nested parentheses. Another myth is that you should use it for every question. This is a trap; the GRE is designed to reward quantitative reasoning, and many problems can be solved more quickly through logic and estimation than by punching in numbers.

GRE Calculator Functions and Explanation

The **calculator allowed in GRE** doesn’t use complex formulas but rather provides a set of functions for basic arithmetic. It respects the standard order of operations (PEMDAS/BODMAS), meaning it will correctly calculate `3 + 4 * 5` as 23, not 35. This is an important feature to be aware of. The core functions are addition, subtraction, multiplication, division, and square root, along with a simple memory feature (MR, MC, M+).

Functionality Table

Here is a breakdown of the key functions available on the on-screen **calculator allowed in the GRE**.

Button / Function	Meaning	Example of Use
+, -, ×, ÷	Basic Arithmetic	Used for addition, subtraction, multiplication, and division.
√ (Square Root)	Finds the square root	Enter a number, then press √. E.g., `144 √` gives 12.
MR (Memory Recall)	Displays the number stored in memory.	If 50 is stored, pressing MR shows 50 on the display.
MC (Memory Clear)	Clears the memory, setting it to 0.	Press to erase any value stored in memory.
M+ (Memory Add)	Adds the current display value to the value in memory.	If memory is 10 and display is 5, M+ changes memory to 15.
C (Clear)	Clears the current calculation entirely.	Resets the calculator to start a new problem.
( )	Parentheses	Allows for grouping operations. e.g. (2+3)*4 = 20.

Understanding these functions is essential for effective use of the GRE calculator.

Practical Examples (Real-World Use Cases)

Example 1: Multi-Step Percentage Calculation

Problem: A store discounts an item priced at $160 by 15%. An employee then buys it with an additional 10% employee discount on the already discounted price. How much does the employee pay?

Calculator Steps:

1. Calculate the initial discount: `160 * 0.15 = 24`.
2. Find the first discounted price: `160 – 24 = 136`.
3. Calculate the employee discount: `136 * 0.10 = 13.6`.
4. Find the final price: `136 – 13.6 = 122.4`.

Interpretation: The employee pays $122.40. Using the **calculator allowed in GRE** helps avoid errors in decimal multiplication and subtraction. A smart test-taker might also practice on a GRE practice test to simulate this under timed conditions.

Example 2: Using the Memory Function for Averages

Problem: A student’s scores on four tests were 88, 92, 81, and 95. What is the average score?

Calculator Steps:

1. Enter `88` and press `M+`. Memory is now 88.
2. Enter `92` and press `M+`. Memory is now 180 (88+92).
3. Enter `81` and press `M+`. Memory is now 261 (180+81).
4. Enter `95` and press `M+`. Memory is now 356 (261+95).
5. Press `MR` to recall the total sum, 356.
6. Press `÷`, then `4`, then `=`. The result is 89.

Interpretation: The average score is 89. The memory function on the **calculator allowed in GRE** is perfect for summing a list of numbers without having to write down intermediate totals, saving time and reducing error.

By practicing with this tool, you’ll build muscle memory for the real exam, making you faster and more confident. Knowing the limitations of the **calculator allowed in GRE** is just as important as knowing how to use it. Explore our guide on the best GRE prep courses for more comprehensive strategies.

Key Factors That Affect GRE Calculator Strategy

Your decision to use the **calculator allowed in GRE** should be a strategic one. Several factors influence when and how you should use it to maximize your score.

1. Time Management: The on-screen interface can be clunky. For simple math (e.g., 15 * 10), mental calculation is faster. Reserve the calculator for “tedious” arithmetic that would take longer to do by hand, like `18.5 * 22`.
2. Estimation Skills: Before calculating, estimate the answer. This helps you catch key-entry errors. If you’re calculating `49 * 4`, you know the answer is near 200. If the calculator shows 1,960, you likely hit an extra key. This is a crucial skill for understanding what is a good GRE score.
3. Problem Complexity: Many GRE questions are about logic, not calculation. They test your ability to simplify problems or recognize patterns. Don’t jump to the calculator; first, see if there’s a simpler conceptual path to the answer.
4. Avoiding Careless Errors: The calculator is a great tool for checking your work if you have extra time. It can also prevent manual arithmetic mistakes on complex multi-step problems, which is a key part of effective GRE test prep.
5. Knowing When NOT to Use It: For questions involving fractions, the calculator’s decimal output might be confusing. It’s often better to work with the fractions directly. A deep GRE math review will help you master these fraction rules.
6. Familiarity with Functions: Practice using the memory (M+) and square root (√) functions before the test. Knowing exactly how they work prevents confusion and saves precious seconds during the actual exam. This familiarity is a cornerstone of any good strategy for the **calculator allowed in GRE**.

Frequently Asked Questions (FAQ)

1. Can I use my own calculator on the GRE?

No. The only **calculator allowed in GRE** is the on-screen calculator provided by ETS during the Quantitative Reasoning sections. Personal calculators are strictly forbidden.

2. Does the GRE calculator have a square root button?

Yes. The on-screen calculator includes a square root (√) function. You enter the number first, then press the √ button to get the result.

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

Yes, it does. The official **calculator allowed in GRE** correctly follows PEMDAS, performing multiplication/division before addition/subtraction. For example, `2 + 3 * 4` will result in 14.

4. Is the calculator available on all sections of the GRE?

No. The calculator is only available during the two Quantitative Reasoning (math) sections. It is not available for the Verbal Reasoning or Analytical Writing sections.

5. Should I use the calculator for every GRE math question?

No, this is a common mistake. Many questions are designed to be solved faster with logic, estimation, or mental math. Overusing the **calculator allowed in GRE** can waste valuable time.

6. How does the memory function (M+, MR, MC) work?

M+ adds the current display value to memory. MR recalls the value from memory to the display. MC clears the memory to zero. This is useful for multi-step problems where you need to save an intermediate result.

7. Can I practice with the official GRE calculator before the test?

Yes. The POWERPREP Online practice tests provided by ETS include a simulator of the official on-screen calculator. Our tool on this page is also designed to mimic its functionality for your practice.

8. What are the biggest limitations of the calculator?

The main limitations are the lack of advanced functions like exponents, trigonometric functions, and logarithms. It’s a basic four-function calculator with square root and memory, so it can’t solve complex algebraic equations on its own.
