OAE Mathematics: Inequalities - Chapter Summary

The quick, convenient lessons in this chapter can be viewed from any mobile or Internet-enabled device, allowing you to take your inequalities study with you on the go. As you work through this chapter, you can develop your understanding of the following:

  • Properties of inequalities
  • Solutions for linear inequalities
  • Graphing 1- and 2- variable and absolute value inequalities
  • Set notation
  • Compound inequalities and systems
  • The absolute-value inequality
  • Quadratic inequalities and systems

There are also lesson quizzes that can show you how inequalities questions on the OAE might be framed and provide you with an important opportunity to practice your inequalities skills. If you get stuck on a quiz question, or have trouble with the material from one of the videos, let our instructors know you need assistance.

Objectives of the OAE Mathematics: Inequalities Chapter

These short, entertaining videos provide appealing and effective demonstrations of the inequalities concepts you can expect to be evaluated on as you work through your OAE certification exam. Make sure to take the lesson quizzes to boost your understanding through practice.

You'll have four and a quarter hours to work through the 150 multiple-choice questions on the OAE Math assessment. Our lesson quizzes model OAE tasks so you can get introduced to the format before your exam date. You'll be tested on five content areas, which account for the following percentages of the test content: geometry and measurement (19%); statistics, probability and discrete mathematics (19%); trig and calculus (19%); math processes and number sense (19%); and algebra, patterns and functions (24%). The topics in this chapter may be found within the algebra, patterns and functions section.

What is an Inequality?

1. What is an Inequality?

Deciding how to spend your money can be a tricky thing. Should you save it, invest it, or enjoy it? Learn how inequalities can help you make your decision!

Solving Linear Inequalities: Practice Problems

2. Solving Linear Inequalities: Practice Problems

Linear inequalities may look intimidating, but they're really not much different than linear equations. In this lesson, we'll practice solving a variety of linear inequalities.

How to Graph 1- and 2-Variable Inequalities

3. How to Graph 1- and 2-Variable Inequalities

So an inequality is just an equation with a less than or greater than symbol. But what is the difference between 1 and 2 variable inequalities? What does have a greater than or equal to symbol change? When do you use a number line instead of a coordinate plane? Get those answers here!

Set Notation, Compound Inequalities, and Systems of Inequalities

4. Set Notation, Compound Inequalities, and Systems of Inequalities

In this lesson, we'll explore the conditions of compound inequalities and learn how to express them using set notation and interval notation. Test you knowledge afterward with a short quiz.
