Chapter 5
Often the most efficient way to get the correct answer to a math problem is to use a strategy rather than just to “do the math.” That’s especially true on the ASVAB, since you cannot use a calculator on the exam. On some math tests, if you get the wrong answer but show that you set up at least some of the math correctly, you’ll still get partial credit. On the ASVAB, you only get credit for a right answer. One advantage of this is that you will get credit for the correct answer regardless of how you get to it.
The two math sections on the ASVAB are called “Arithmetic Reasoning” and “Mathematics Knowledge.” Together they form the quantitative half of the Armed Forces Qualifying Test (AFQT), so you’ll want to do well on these sections no matter what your ultimate vocational aim in the military.
The Arithmetic Reasoning (AR) section tests your ability to handle arithmetic word problems. The CAT version of this section gives you 39 minutes to answer 16 questions, while the paper-and-pencil version gives you 36 minutes for 30 questions. This section is designed to measure your ability to apply reasoning to solve problems involving common math concepts. Many of the questions will be in the format of word problems. Typical AR topics involve number properties, rates, percentages, ratios, proportions, averages, and unit conversions.
The Mathematics Knowledge (MK) section tests your understanding of a wide range of concepts in applied arithmetic, algebra, and geometry. The CAT version gives you 20 minutes to answer 16 questions; the paper-and-pencil version gives you 24 minutes to answer 25 questions. This section is designed to measure general mathematical knowledge. You may see the occasional word problem on the MK section of the ASVAB, but in general the questions are more direct than the word problems found on the AR section. For this reason, you are given less time per question on this section than on the AR section.
