Ch 14: PLACE Mathematics: Absolute Value Problems

About This Chapter

The PLACE Mathematics exam tests prospective Colorado math teachers' overall knowledge of their subject. The required exam features a section on absolute value. This study guide provides an in depth examination of absolute value to help you prepare for the PLACE Mathematics. Each interactive lesson also provides you with questions in the test's same format.

PLACE Mathematics Exam: Absolute Value Problems - Chapter Summary

Absolute value is a key component of the PLACE Mathematics exam. This study guide covers it in detail. The brief video lessons go over the meaning of absolute value and help you work through a number of practice problems as well. By the end of the chapter, you will have mastered exam topics such as:

  • The definition of absolute value
  • Strategies for solving absolute value problems
  • Graphing absolute values
  • Graphing absolute value equations
  • Transforming absolute value graphs

Each lesson breaks down a larger concept into bite-sized chunks that are easy to review. Our instructors use engaging animations and illustrations to make your test preparation fun. Studying each of the lessons slowly and then making sure to master each type of problem can lead to your success on the test.

PLACE Mathematics Exam: Absolute Value Objectives

The multiple-choice PLACE Math exam has five areas: foundations of mathematics, functions and relations, probability, measurement and geometry, and calculus. The absolute value section of the exam is part of the functions and relations section of the PLACE Mathematics exam. This section examines your knowledge of the many different types of functions, their graphs, and their relation to the real world.

Absolute value concepts could possibly factor into different and more complex questions. As you go through the lessons, the study guide will help you connect the absolute value ideas with other math topics, particularly polynomial, rational, and radical functions.

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!

Finding the Absolute Value of a Real Number

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.

Solving Absolute Value Practice Problems

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.

How to Graph an Absolute Value and Do Transformations

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!

Graphing Absolute Value Equations: Dilations & Reflections

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.
