# Ch 3: NES Middle Grades Math: Properties of Numbers

### About This Chapter

## NES Middle Grades Math: Properties of Numbers - Chapter Summary

This chapter consists of definitions, formulas and examples that are associated with the properties of numbers. Review its online video and text lessons, which can help you prepare for the NES Middle Grades Math examination. Brush up on familiar concepts as you further explore the fundamentals of the three basic number properties: the commutative property, the distributive property and the associative property. This chapter could enhance your ability to:

- Express the statements of the associative, distributive and commutative properties
- Solve problems with the commutative property of addition and the multiplication property of zero
- Use the addition, subtraction, multiplication and division properties of equality
- Explain the symmetric, transitive and reflexive properties of equality

Experienced educators narrate these video lessons and guide you in mastering the above material as you prepare for the NES Middle Grades Math examination. The animated videos are short and entertaining. Offered online, all of the lessons are easily accessible via your mobile device.

### NES Middle Grades Math: Properties of Numbers Chapter Objectives

Demonstrate your ability to understand numbers and operations when you begin the *Number Sense and Operations* content domain of the NES Middle Grades Math examination. One of four content domains, *Number Sense and Operations* amounts to 17% of the entire assessment score. Draw upon the knowledge you gained from this chapter and your previous education when answering the examination's 150 multiple-choice questions. Your correct answers on the properties of numbers and other math topics could qualify you for a middle grades mathematics teaching endorsement. You'll be granted up to four hours and 15 minutes to complete the computer-based test.

### 1. 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.

### 2. Commutative Property of Addition: Definition & Example

This lesson will explain the commutative property of addition, as well as provide examples of how this property is used. A quiz to test your knowledge will follow the lesson.

### 3. 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.

### 4. Distributive Property: Definition, Use & Examples

After completing this lesson, you will be able to state the distributive property and apply it to various types of problems. You will also be able to accurately perform the mathematical operations that are involved with the distributive property.

### 5. 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.

### 6. Addition Property of Equality: Definition & Example

After watching this video lesson, you should be able to use the addition property of equality to help you solve problems. In addition, you can learn the formula for this property.

### 7. Subtraction Property of Equality: Definition & Example

In this video lesson, we look at the subtraction property of equality. Learn how it helps you to solve problems and how it keeps equations the same. Learn what you must do to both sides of an equation.

### 8. Multiplication Property of Equality: Definition & Example

After watching this video lesson, you will learn to use the multiplication property of equality to help you solve problems in math. You will also learn the formula for this property.

### 9. Division Property of Equality: Definition & Example

In this video lesson, you will learn about the division property of equality, its formula, and how you can use it to help you solve problems where you are looking for an unknown number.

### 10. Reflexive Property of Equality: Definition & Examples

After watching this video lesson, you will understand the reflexive property of equality. You will learn what the formula for this property looks like and how you can use it to help you solve problems.

### 11. Symmetric Property of Equality: Definition & Examples

Have you ever finished a math problem only to see that the teacher's answer was written backwards? Find out why your answer is correct in this lesson on the symmetric property of equality!

### 12. Transitive Property of Equality: Definition & Example

After watching this video lesson, you will understand how the transitive property of equality works when you have two equations that are equal to each other. Learn the formula for this property and how you can use it to help you solve problems.
