Use this simulator to get a feel for the basic functions available on the actual GRE on-screen calculator. Perform simple arithmetic and see how the results are displayed, alongside key information about the GRE’s calculator policy.

What is “Can You Use a Calculator on the GRE?”

The question “can you use a calculator on the GRE?” refers to the official policy regarding calculator usage during the Graduate Record Examinations (GRE). Unlike some other standardized tests, the GRE does indeed provide a calculator for its Quantitative Reasoning section. However, it’s crucial to understand that this isn’t a physical calculator you bring yourself, nor is it a full-featured scientific calculator. It’s a basic, on-screen calculator integrated directly into the testing software.

Who should use it? Every test-taker taking the GRE General Test will have access to this on-screen calculator during the Quantitative Reasoning sections. It’s designed to help with tedious arithmetic calculations, allowing test-takers to focus more on problem-solving strategies rather than manual computation. While it’s available, it’s not always necessary, and sometimes using it can even slow you down if the calculation is simple enough to do mentally.

Common misconceptions:

• “I can bring my own calculator.” Absolutely not. Bringing any external calculator is strictly prohibited and will lead to disqualification.
• “It’s a scientific calculator.” This is false. The GRE calculator is basic, offering only addition, subtraction, multiplication, division, and square root functions, along with memory functions.
• “I need to use it for every problem.” Many GRE quantitative problems are designed to be solved conceptually or with minimal calculation. Over-reliance on the calculator can waste valuable time.
• “It’s available for all sections.” The calculator is only available for the Quantitative Reasoning sections of the GRE General Test.

“Can You Use a Calculator on the GRE?” Formula and Mathematical Explanation

Since “can you use a calculator on the GRE?” isn’t a mathematical formula in itself, but rather a policy question, the “formula” here refers to the basic arithmetic operations the GRE’s on-screen calculator can perform. Understanding these operations and their limitations is key to effective use.

The GRE calculator functions like a standard four-function calculator with an added square root feature. Its operations are straightforward:

• Addition (+): Combines two numbers. Example: A + B = Sum
• Subtraction (-): Finds the difference between two numbers. Example: A - B = Difference
• Multiplication (x): Finds the product of two numbers. Example: A x B = Product
• Division (/): Divides one number by another. Example: A / B = Quotient
• Square Root (√): Calculates the non-negative square root of a number. Example: √A = X (where X * X = A)
• Memory Functions (M+, M-, MR, MC): These allow you to store, add to, subtract from, recall, and clear a single value in the calculator’s memory.

Step-by-step derivation (of a basic calculation):

1. Input First Number: Type the first number (e.g., 125).
2. Select Operator: Click the desired operation (e.g., +). The display will show the first number, and the calculator is ready for the second.
3. Input Second Number: Type the second number (e.g., 75).
4. Execute Calculation: Click the = button. The result (e.g., 200) will appear on the display.

This simple sequence is the core “formula” for using the GRE’s on-screen calculator. It’s designed for efficiency, not for complex algebraic or trigonometric functions.

Practical Examples: Using the GRE On-Screen Calculator

Understanding when and how to use the GRE’s on-screen calculator is crucial. Here are two practical examples demonstrating its utility and limitations.

Example 1: Calculating a Percentage Increase

Scenario: A company’s revenue increased from $12,500 to $15,750. What is the percentage increase?

Inputs & Steps:

1. Calculate the absolute increase: 15750 - 12500
2. Divide the increase by the original amount: (Increase) / 12500
3. Multiply by 100 to get the percentage: (Result) * 100

Calculator Output & Interpretation:

• On the GRE calculator:
  1. Type 15750, then -, then 12500, then =. Display shows 3250.
  2. Type /, then 12500, then =. Display shows 0.26.
  3. Type *, then 100, then =. Display shows 26.
• Result: The percentage increase is 26%.
• Interpretation: This demonstrates how the basic arithmetic functions are sufficient for common business math problems on the GRE. The calculator helps avoid errors in multi-step calculations.

Example 2: Finding the Side Length of a Square from its Area

Scenario: A square garden has an area of 289 square feet. What is the length of one side of the garden?

Inputs & Steps:

1. The area of a square is side * side (s²). To find the side, you need the square root of the area.
2. Calculate the square root of 289.

Calculator Output & Interpretation:

• On the GRE calculator:
  1. Type 289.
  2. Click the √ (square root) button.
• Result: The display shows 17.
• Interpretation: The length of one side of the garden is 17 feet. This example highlights the utility of the square root function, which is often needed for geometry problems involving areas or distances.
