Ch 1: WEST Math: Properties of Real Numbers

About This Chapter

Washington State has replaced the WEST Mathematics exam with the National Evaluation Series (NES) Mathematics test. This course offers engaging video lessons and lesson quizzes to help you prepare for the NES Mathematics test.

WEST Math: Properties of Real Numbers - Chapter Summary

The lessons in this chapter will help prepare you for the WEST Mathematics exam by discussing the different types and properties of numbers. Our short, engaging video lessons cover topics such as:

  • Number lines
  • Commutative property
  • Associative property
  • The multiplication property of zero
  • Greatest common factor
  • The least common multiple
  • Order of operations
  • Prime numbers
  • Composite numbers
  • Prime factorization

Our experienced instructors will guide you through each topic and are available to answer any questions you may have. Self-assessment quizzes and written transcripts accompany each video lesson to help ensure that you get a firm grasp on the material and are ready to take the exam.

WEST Math: Properties of Real Numbers Objectives

The WEST Mathematics exam tests your knowledge of arithmetic, algebra, geometry, trigonometry, calculus and statistics to determine your candidacy for a Washington State teaching certificate. The four hour and fifteen minute long computer-based exam consists of 150 multiple choice questions. This Properties of Real Numbers chapter of our WEST Mathematics: Practice and Study Guide course helps prepare you for the mathematical processes and number sense portion of the exam, which constitutes about 19% of the total mathematics exam. Self-assessment quizzes at the end of each lesson will let you gauge whether or not you understand the material, as well as introduce you to the types of questions you'll encounter on the exam.

What are the Different Types of Numbers?

1. What are the Different Types of Numbers?

Learn all of the different types of numbers: natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers. This video lesson teaches you how to classify any numbers you come across.

Graphing Rational Numbers on a Number Line

2. Graphing Rational Numbers on a Number Line

Number lines have many uses both in mathematics and everyday life. This lesson will teach you how to graph numbers on a number line and give real-world examples of how to use number lines.

The Commutative Property: Definition and Examples

3. The Commutative Property: Definition and Examples

There are three major properties that deal with the addition and multiplication of numbers. One of those properties is the commutative property. This lesson will define and give examples of the commutative property and how it works.

The Associative Property: Definition and Examples

4. The Associative Property: Definition and Examples

There are three basic number properties that help to form the backbone of algebra. One of those properties is the associative property. This lesson will define the associative property and give some examples of how it works.

The Multiplication Property of Zero: Definition & Examples

5. The Multiplication Property of Zero: Definition & Examples

The number zero has different rules than other numbers; it behaves according to it's own unique properties. This lesson will define the multiplication property of zero and give some examples of how it works.

How to Find the Greatest Common Factor

6. How to Find the Greatest Common Factor

If the factors of a number are the different numbers that you can multiply together to get that original number, then the greatest common factor of two numbers is just the biggest one that both have in common. See some examples of what I'm talking about here!

How to Find the Least Common Multiple

7. How to Find the Least Common Multiple

The least common multiple of two numbers is the smallest number that can be divided evenly by your two original numbers. See some examples of what I'm talking about here!

What Is The Order of Operations in Math? - Definition & Examples

8. What Is The Order of Operations in Math? - Definition & Examples

The order of operations is the steps used to simplify any mathematical expression. In this video, learn how to solve problems using these steps and easy tricks to remember them.

How to Find the Prime Factorization of a Number

9. How to Find the Prime Factorization of a Number

The prime factorization of a number involves breaking that number down to its smallest parts. This lesson will show you two different ways to discover the prime factorization of any number.
