# Ch 14: GACE Math: Absolute Value Problems

### About This Chapter

## GACE Math: Absolute Value Problems - Chapter Summary

The brief, effective video lessons and companion video transcripts in this chapter illustrate the kinds of absolute value topics you can expect to be tested on as you work through your GACE Math assessment. Chapter topics include:

- The definition of absolute value
- How to find a real number's absolute value
- Graphing absolute value
- Dilations and reflections in absolute value graphs

The lesson quizzes let you practice solving absolute value problems and allow you to see how well you understand the material. If you get stuck on a problem, be sure to let our instructors know you need help.

### 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. 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.

### 3. 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.

### 4. 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!

### 5. 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.
