### About This Chapter

## MTEL Middle School Math/Science: Properties of Equality & Inequality - Chapter Summary

This chapter, its lessons and assessments have been assembled to help you review the concepts of equality and inequality. It also reviews the properties of equality that may be helpful when you take the MTEL: Mathematics/ Science (Middle School) exam. After these lessons, you should have a firm understanding of the following properties of equality:

- Addition
- Subtraction
- Multiplication
- Division
- Symmetric
- Transitive
- Reflexive
- Substitution

As you watch these videos, be sure to read the lesson transcripts that will help you retain the information presented in them. Also, take the lesson quizzes to discover the topics you have mastered and the topics you haven't. Then, use the video tags of the quiz results to go to the locations of the lessons that explain the topics you missed and study them to improve your understanding of the material.

### MTEL Middle School Math/Science: Properties of Equality & Inequality - Chapter Objectives

Individuals seeking certification as middle-grades math and science teachers in Massachusetts must pass the Massachusetts Tests for Educator Licensure (MTEL): Mathematics/Science (Middle School) exam. This four-hour, computer-based certification exam involves completing 100 multiple-choice questions and two open-response assignments. This chapter will help refresh your understanding of the properties of equality, a topic that you will be tested on during the patterns, relations, and algebra section of the exam. The approximate test weight of this portion is about 12%.

### 1. What is an Inequality?

Deciding how to spend your money can be a tricky thing. Should you save it, invest it, or enjoy it? Learn how inequalities can help you make your decision!

### 2. 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.

### 3. 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.

### 4. 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.

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