Ch 22: WEST Middle Grades Math: Absolute Value

About This Chapter

The WEST Middle Grades Mathematics certification exam has been replaced with the NES Middle Grades Mathematics test. In preparation for this exam watch these lesson videos on finding the absolute values of equations and real numbers.

NES Middle Grades Mathematics: Absolute Value - Chapter Summary

As part of a review course for the National Evaluation Series (NES) Middle Grades Mathematics test, this chapter will aid in your review of finding and graphing absolute values. Watch our professional instructors as they prepare you for questions related to:

  • Evaluating absolute value expressions
  • Solving for the absolute value of an equation
  • Graphs and transformations of absolute values
  • Finding the absolute values of real numbers

Further reinforce your comprehension of the material in this chapter by completing the lesson worksheets and quizzes that accompany the lesson videos. With the results from your quizzes you can discover topics you haven't fully mastered and then organize a review of those topics with video tags. If afterward you feel you could still improve your understanding, try reading over the written lesson transcripts.

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.
