ASVAB math: what’s on it and how to practice

There are two math subtests, Arithmetic Reasoning and Mathematics Knowledge, and both count toward your AFQT. Arithmetic Reasoning gives you word problems; Mathematics Knowledge tests high school math principles. You can’t use a calculator on any version, so all ASVAB math is done by hand, with scratch paper.

Arithmetic Reasoning and Mathematics Knowledge

Arithmetic Reasoning has the longest time limit on the computer test. Both subtests also feed many line scores, so math points help with jobs as well as enlisting.

Can you use a calculator on the ASVAB?

No. The official site explains that the ASVAB is an employment test, and some jobs need basic math and hand calculations without a calculator. The at-home PiCAT bans calculators too, and asks you to have scratch paper and a pencil.

If calculators were allowed, the official site says, scores would be adjusted to cancel out the advantage, so the people who qualify would stay the same.

Is there an ASVAB math formula sheet?

The official pages don’t mention one, and the official sample questions don’t come with formulas. So practice the formulas you use from memory before test day.

How to practice ASVAB math

  1. Work the official Arithmetic Reasoning and Mathematics Knowledge sample questions on paper.
  2. Note whether you miss questions because of the math or because of reading the problem.
  3. Drill the weak spots by hand, without a calculator.
  4. Finish with mixed practice so you get used to switching between word problems and pure math.
