Yes, you can use a calculator on GED,but only in designated parts of the exam and only the official on-screen model. The calculator on GED is the TI-30XS Multiview scientific calculator, provided digitally within the test interface. You cannot bring your own device to the testing center or use a physical calculator during the online exam.
The calculator is permitted for 40–44 questions in Part 2 of the Mathematical Reasoning section. The first part of Math,just 5 questions,is calculator-prohibited and focuses on basic arithmetic and quantitative reasoning. Additionally, the calculator may be available for select data-based questions in the Science and Social Studies sections, though it’s rarely needed there.
How to Prepare with the Approved Calculator
Since the calculator on GED is built into the exam software, you must practice with the exact same version during preparation. The GED Testing Service offers a free, functional replica on GED.com and in the GED Ready practice tests. Familiarity with its buttons,especially for fractions, exponents, and square roots,is essential for speed and accuracy.
Many test takers lose time because they haven’t practiced with the TI-30XS. Others misuse it on simple problems, slowing down unnecessarily. Use it strategically,for multi-step calculations, percentages, or scientific notation.
Remember: the calculator on GED won’t compensate for gaps in math understanding. It’s a tool to enhance efficiency, not replace reasoning.
Mastering its use reduces errors and builds confidence on test day. Knowing when and how to use the calculator on GED is part of smart test-taking.
