Are you planning to take a high school equivalency test in math? If so, you should start thinking about calculators. Each test has specific rules for calculator use. The GED test and TASC test both use the TI-30XS scientific calculator. The HiSET exam uses a simpler four-function calculator. Which test you can take depends on your state.
The GED Mathematical Reasoning test is given on a computer. A Texas Instruments TI-30XS on-screen calculator will be available during the test on most questions. It's even available on some science and social studies questions. Try this tutorial to get familiar with the calculator: GED Test Calculator Tutorial.
Testing centers do not provide hand-held calculators. Check with your test center to ask specific questions about calculators. In the U.S., the GED test is only given on paper if you have been approved for special accommodations. Most students are expected to use the on-screen calculator.
In Canada, testing centers will provide you with the Casio FX260 handheld calculator for part of the paper-based math test. On the computer-based test, students will have access to the on-screen TI-30XS. Canadian test-takers can also bring their own Casio FS260 calculator.
International students cannot use a handheld calculator. They must use the on-screen calculator.
The TASC math subtest covers basic math, word problems, algebra, and geometry. You'll have 55 minutes to complete the test, or 60 minutes if you're taking the test in Spanish. You may use a calculator for the TASC test math subtest.
The TI-30XS is the preferred calculator for the TASC test. Other scientific calculators may be allowed subject to state and area approval.
Any alternative calculator must meet the following criteria:
Test coordinators should have a list of approved alternative calculators. Contact your local test center for details.
The HiSET mathematics subtest requires basic math, measurement, estimation, data interpretation, and logical thinking. The test is 90 minutes long and you may use a calculator throughout. The testing center will provide a basic four-function calculator. For the computer-based test, an on screen calculator is available. If you'd like to familiarize yourself with the on-screen calculator, see the HiSET Exam Calculator Tutorial.
The TI-30XS is a scientific calculator, so it's a little more difficult to use. It's more advanced than the kind of calculator commonly used to balance checkbooks. Even many of today's college graduates are unfamiliar with the higher functions of scientific calculators.
Don't worry though. High school equivalency tests use only the more basic functions of the TI-30XS. Take some time to look at the TI-30XS, or the alternate calculator you'll use on your test. You'll want to learn the location of the keys and the functions they perform.
Learn how to:
Does it sound complicated? Maybe, but only if you haven't practiced. Once you have some hands on experience, you’ll see that it’s not too difficult.
Again, don't worry. High school equivalency tests call for only basic calculator knowledge. Even so, it still pays to practice beforehand. Understanding the calculator can help you understand the math you'll need to know. The TI-30XS is worth learning.
Understanding also goes a long way toward reducing math anxiety. Try using the TI-30XS while taking a free GED practice test. Familiarize yourself with its functions before sitting down for the exam. The better prepared you are, the better your score will be.
