Calculate Your Advantage: Utilizing a Calculator on the GRE

GRE Calculator Availability and Usage

When preparing for the GRE, a common question is: Do you get a calculator on the GRE? The simple answer is yes, but exclusively in the form of an on-screen calculator provided during the quantitative section. This basic calculator is available for questions involving calculations but has limited functionality compared to traditional physical calculators.

Calculator Functionality and Restrictions

The on-screen calculator provided during the GRE is basic and often described as clunky and awkward. It is designed for simple arithmetic like solving decimals, ratios, or square roots and less efficient for more complex mathematical operations. The calculators slow response can lead to delays and possible errors, recommending its use primarily for complex problems where mental math would be inefficient or time-consuming.

Strategies for Optimal Calculator Use

Effective GRE preparation involves knowing when and how to use the provided calculator. It is advisable to rely on mental math for simpler problems to save time. For more complicated arithmetic that takes longer than five seconds to solve, using the calculator is recommended. Familiarize yourself with the order of operations and keyboard input to enhance efficiency and reduce errors. Always double-check for any error messages that might indicate a mistake in your entries.

Supplemental Tools and Preparation Resources

In addition to practicing with the on-screen calculator, prepare by using the array of resources available through ETS, such as the Official GRE Prep, GRE practice tests, and GRE math review. Further, Khan Academy videos can aid in strengthening your quantitative skills and adapting to the calculation tools allowed during the GRE.

Do You Get a Calculator on the GRE?

Yes, you can use a calculator on the GRE. However, personal calculators are not permitted. Instead, the GRE provides an on-screen calculator that's basic yet functional for the Quantitative Reasoning sections of the test. This tool can perform basic operations such as addition (+), subtraction (-), multiplication (*), and division (/). It also includes functions for calculating square roots, adding decimals, and changing the sign of numbers.

The on-screen calculator is beneficial for tackling more complex arithmetic, solving problems involving decimals, ratios, or square roots, and can ultimately save you time and mental energy. While using the calculator, it's important to note that it is more basic than most handheld calculators and lacks advanced functions such as exponents and logarithms. It's crucial to practice with the GRE calculator to make effective use of it on the test day.

Despite its convenience, the on-screen GRE calculator may slow you down or lead to mistakes if not used carefully. It's advised to use the calculator for tasks that are error-prone if done manually or where precision is necessary. Always double-check calculator inputs and outputs to ensure accuracy, especially under exam pressure.

Key Functions and Usage Tips

The GRE calculator allows basic functions and has additional capabilities including parentheses for grouping numbers, and memory keys (MR, MC, M+) for storing and recalling numbers. To transfer answers directly from the calculator to the answer box, use the provided functions efficiently. Remember, using the calculator effectively requires practice, particularly in deciding when and how to use it to enhance your test performance without wasting valuable time.

In summary, while the GRE provides a calculator, it's essential to become familiar with its functions and limitations to utilize it effectively during the exam. Avoid reliance on the calculator for simple calculations that can be done quicker manually, and practice thoroughly to maximize your efficiency and accuracy.

GRE Calculator Usage: Example Problems

Basic Arithmetic

Consider needing to calculate 5% of 350 during the test. Use the calculator to multiply 350 \times 0.05 to get 17.5. This quick calculation assists in efficiency during the exam.

Compound Interest Calculations

For a question involving compound interest, suppose you want to find the amount on a principal of $4,000 compounded annually at 3% for 5 years. Use the formula A = P(1 + r)^n. Input 4000 \times (1 + 0.03)^5 into the calculator to get the result.

Statistical Data Analysis

In a data interpretation set, you might need to calculate the standard deviation of a given set of numbers. Input the data into the calculator's statistics mode to find the mean and deviations efficiently, saving precious time for analysis and interpretation.

Geometry Problems

When solving geometry problems, such as finding the area of a circle with a radius of 7cm, formula Area = \pi r^2 is used. Input 3.14 \times 7^2 into the calculator to promptly get 153.86 cm^2.

Algebraic Equations

For solving equations like 3x + 4 = 19, isolate x by first subtracting 4 and then dividing by 3. A calculator streamlines these basic algebraic manipulations, resulting in x = 5 efficiently.
