About Mathematics Knowledge
Mathematics Knowledge tests your understanding of mathematical concepts beyond word problems. Unlike Arithmetic Reasoning which focuses on applied math, MK tests pure mathematical knowledge including algebra, geometry, and basic number theory. On the CAT-ASVAB, you have approximately 23 minutes for 15 questions. As an AFQT component, your MK score directly impacts your enlistment eligibility. Questions cover topics from basic algebra (solving equations, inequalities) to geometry (area, volume, angles) and some basic probability and statistics. A solid foundation in high school math is essential for this section.
Topics Covered
Sample Questions
Study Tips for Mathematics Knowledge
Memorize Key Formulas
Know the formulas for area, perimeter, volume, and the Pythagorean theorem. These appear frequently and are not provided on the test.
Practice Algebra Daily
Solving equations and simplifying expressions are the most common MK question types. Practice these skills until they become automatic.
Review Geometry Basics
Know the properties of common shapes (triangles, circles, rectangles). Understand how to calculate area, perimeter, and volume.
