ASVAB Mathematics Knowledge Exam Format

Depending on whether you are taking the CAT-ASVAB or the P&P ASVAB, there are different numbers of questions asked and time allotted.


15 Questions

ASVAB math knowledge tests your understanding of abstract concepts such as equations and algebra and geometry.

Unlike the arithmetic reasoning exam, candidates are not asked
word-based question problems that solely rely on addition, subtraction,
multiplication, and division.

  • Math Vocabulary

    To perform well on the ASVAB math knowledge exam, candidates must know their math vocabulary. This includes terms such as improper fractions, integers, reciprocals, exponents, prime numbers, and factorials – among many others. Without knowing the vocabulary, you will not know how to answer questions.

  • Fractions

    Fractions are routinely examined on the math knowledge test. Candidates are expected to know how to add, subtract, multiply, and divide fractions. You should also know how to find common denominators between two fractions. Improper fractions also get tested and knowing how to convert fractions to decimal form.

  • Algebra

    Algebra is a branch of math that deals with symbols to handle equations. Candidates must know how to solve equations for x; to reduce equations to their simplest form; and to add and subtract exponents. You should also know how to find square roots, factor three-term equations, and solve quadratic equations.

  • Geometry

    Geometry is that branch of math that concerns sizes, shapes, angles, and dimensions. On the ASVAB math knowledge exam, candidates will be asked how to calculate angles; the area and perimeter of shapes such as triangles and squares; and how to calculate the volume an object occupies.

  • Probability

    Expect to be asked questions on other topics such as probability. You may be asked how to find factorials – such as 6! Probability questions on the ASVAB exam are typically not too difficult, but you should understand how to solve these problems regardless.

  • Decimals and Percentages

    Candidates will be asked questions on percentages, decimals, and fractions – and how to convert one form to another. For example: 0.6 is the same as 6/10 which is the same as 60% - the first, a decimal; the second, a fraction; and the third; a percentage. You should know how to manipulate figures in this way.

Test Taking Tips!

To succeed at the ASVAB mathematics knowledge test, candidates must study in the weeks and months leading up to the exam practicing as many ASVAB test practice questions as possible.

  • Never rush. Try not to get frustrated with math problems, tempting though that may be. If you are struggling to answer a question, do not waste too much time on it. Better to spend more time on other, easier questions than get stressed and run out of time.
  • Understand the Question. Unless you understand what the math question is asking, you cannot form a plan of action. Take a few seconds to put together a plan and execute that plan of action in a methodical and logical manner. Do not jump into the answer at rapid speed. Take your time – but not too much time.
  • Eliminate wrong answers. On multiple-choice ASVAB math knowledge questions, there are often two obvious wrong answers and two answers that more approximate the correct solution. Try to identify these outsider answers, if possible, and eliminate them. Then, work out the problem and identify the correct answer. At worst, this gives you a 50:50 chance of guessing the right answer – but doing so in an educated and informed manner.
  • Know the terms and phrases. In the weeks leading up to the ASVAB exam, it is important that you take the time to learn important phrases. We included many of these terms above in the “What Gets Tested” section. Unless you understand the vocabulary of math knowledge, you will struggle before you even begin.
  • Take ASVAB test practice questions. The more practice problems you try, the more you acquire the mental skills necessary to identify your strengths and to discover where your weaknesses lie – and to plug those gaps in your knowledge base. Practicing ASVAB questions also lets you know whether you are prepared to take the real thing.
