The GED Test

If you're reading this, you're likely preparing to take the GED Test. Congratulations! Preparing for the GED is important in all areas, and students should do everything they can to make sure they're ready for testing. The GED Mathematical Reasoning Test is a sub-test area in which you'll be asked questions in two main focus areas: algebraic problem solving and quantitative problem solving. How can you prepare for this portion of the GED test? Let's take a look.

Tools for the GED Mathematical Reasoning Test

Okay, so you have a solid understanding of what the GED is and you've mastered the content necessary to rock the GED Mathematical Reasoning Test. You're just about ready! The last thing on your checklist is to fully understand what tools you'll need to take the test, so you can maximize time and energy.



The good news is you don't have to go out and buy a fancy-pants calculator for the test. A Texas Instruments TI-30XS will be available to you on-screen for the portions of the test during which it is applicable. Before hitting the test, familiarize yourself with this on-screen tool by visiting sites that provide practice and explanation for you. More about this in the 'How' section below.

If you prefer to bring your own, the TI-30XS Multiview Scientific Calculator is the only instrument allowed for U.S. test takers. You'll need to bring your own as the testing centers don't supply them for you.


On questions allowing calculator usage, a 'Calculator' button will be available in the blue toolbar at the top of your computer screen, just above the question. To open the calculator, just click this button. Easy-peasy.

You will likely need to adjust the size of the calculator and move it so you can see both the question and the calculator. To adjust this, simply click the portion of the window labeled 'Calculator' and drag the dots at the bottom of the window to place and size it. When you're finished, you can close the calculator by hitting the 'X' button.

To help you out you'll also have a 'Calculator Reference' button. This is your go-to for understanding how to use the tool. Clicking this icon will give you information on key operations as well as operations for:

  • Basic arithmetic
  • Percentages
  • Scientific notation
  • Fractions
  • Mixed numbers
  • Powers and roots
