### About This Chapter

## MTTC Mathematics (Elementary): Absolute Value - Chapter Summary

This chapter's lessons on absolute value are geared towards equipping learners with the knowledge necessary to ace related portions of the MTTC Mathematics (Elementary) exam. The lessons highlight all of the following:

- The definition of absolute value
- Evaluating and solving absolute value equations and expressions
- Completing practice problems with absolute values
- Graphing and transforming an absolute value
- Dilations and reflections in absolute value graphing
- Real numbers and absolute values

Review the content through either a video or transcript of the lesson. You'll find both options easy to navigate. The transcript is full of important terms highlighted in bold and the timeline feature allows you to quickly jump to each of the videos' main topics.

### 1. What is an Absolute Value?

When we're talking and comparing numbers, we often don't care whether its positive or negative, just how big it is. This is often called the magnitude of a number and we find it by taking the absolute value. Learn all about it here!

### 2. How to Evaluate Absolute Value Expressions

Substituting values into absolute values doesn't have to be too hard, but it can be if you're given deceiving beginning information. See if you're up to it by checking out this video!

### 3. How to Solve an Absolute Value Equation

Once you get familiar with any new operation, the next step in any algebra class is to learn how to solve equations with that operation in them. Absolute values are no different. Solve absolute value equations here!

### 4. Solving Absolute Value Practice Problems

There are many easy mistakes to make when solving absolute value equations. Learn how to avoid those mistakes here by working on examples of absolute value equations with operations on the inside and the outside of the absolute value.

### 5. How to Graph an Absolute Value and Do Transformations

Absolute value graphs normally look like the letter 'V', but transformations can change that 'V' in a number of different ways. As well as teaching you how to graph absolute values, this video will focus on a specific group of transformations called translations. Learn all about what that means here!

### 6. Graphing Absolute Value Equations: Dilations & Reflections

Although a basic absolute value graph isn't complicated, transformations can make them sufficiently confusing! In this lesson, you'll practice different transformations of absolute value graphs.

### 7. Finding the Absolute Value of a Real Number

You can find the absolute value of any real number. This lesson will define absolute value, explain what real numbers are and give the steps to finding the absolute value of any real number.
