On the paper version of the ASVAB, the Mathematics Knowledge subtest consists of 25 questions, and you have 24 minutes to complete the subtest. The CAT-ASVAB offers 16 questions in 20 minutes. You don’t necessarily have to rush through each calculation, but the pace you need to set doesn’t exactly give you time to daydream. You have to focus and concentrate on solving each problem quickly and accurately. And no calculators are allowed! 

The Mathematics Knowledge subtest usually contains only one or two questions testing each specific mathematical concept. For example, one question may ask you to multiply fractions, the next may ask you to solve a mathematical inequality, and the question after that may ask you to find the value of an exponent.

To qualify for certain jobs in the military, you have to score well on the Mathematics Knowledge subtest. You must also do well on this subtest, which is part of the AFQT, to enlist.
