ASVAB Math: Factorials in Math Chapter Objectives
The Armed Services Vocational Aptitude Battery (ASVAB) tests a candidate for the U.S. Military's understanding of basic principles in several academic fields. This test can be taken throughout the year by anyone who is eligible to join the military but is mostly offered to high school students.
There are 25 multiple-choice questions in the paper-based Math Knowledge subtest that you will have to solve within 24 minutes.
A computerized version of the exam also exists, and it contains 16 questions and a 20-minute time limit. The Math Knowledge section includes some questions about factorials. This study guide is designed to teach you everything you'll need to know to answer those questions. After studying this chapter, you will be able to explain the definition of factorials, understand what they are used for, and demonstrate how to solve problems with factorials in them and use different factorial formulas.
1. What Is a Factorial?
Maybe it's because I'm a math teacher, but when I watched the Olympics I found myself thinking about how many different ways the swimmers could have finished the race. In this video, you'll learn the answer to this question, why it's important and how it lead to the invention of the mathematical operation called the factorial.
2. Factorial Practice Problems
While the definition of factorial isn't complicated, it's easy to make them trickier by throwing a lot of them together and adding in some fractions. Test your skills here with some algebraic examples that make you use factorials without many numbers.
3. How to Use Factorial Notation: Process and Examples
Watch this video lesson to learn about factorial notation. Understand what it means so that you can handle it like a pro. Also see what happens when we divide factorials.
