About This Chapter

As you prepare for the NES Middle Grades Mathematics exam, watch these lessons to prepare for questions about evaluating, graphing and solving problems with absolute values.

NES Middle Grades Math: Absolute Value - Chapter Summary

These lessons have been put together to help you study for questions on the National Evaluation Series (NES) Middle Grades Mathematics exam related to absolute value. Follow along with our professional instructors to prepare for exam questions that may require you to:

  • Define absolute value
  • Evaluate absolute value expressions and solve absolute value equations
  • Graph absolute value equations and complete transformations
  • Find absolute values of real numbers

These lessons are accompanied by quizzes that you can use to identify topics that you don't understand. You can then reinforce your understanding of these topics by using the embedded video tags to return to the locations in the videos that explained them. Once you've completed these lessons and improved your understanding of areas of weakness, make sure you understand the material well enough for the NES Middle Grades mathematics by taking the practice chapter exam.

What is an Absolute Value?

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!

How to Evaluate Absolute Value Expressions

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!

How to Solve an Absolute Value Equation

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!

Solving Absolute Value Practice Problems

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.

How to Graph an Absolute Value and Do Transformations

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!

Graphing Absolute Value Equations: Dilations & Reflections

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.

Finding the Absolute Value of a Real Number

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.
