# Ch 3: Inequalities

### About This Chapter

Watch our math video lessons and learn all you need to know about inequalities. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these topics.

Inequalities are similar to equations with the exception that inequalities are written using greater than, less than, or not equal to signs instead of an equal to sign. An inequality can easily be explained as anything which is not equal. Inequalities can be found in real life, not just in a mathematical context, which you will discover in these lessons.

When working with inequalities in math, you'll need to know how to graph them. In the lessons, you'll be taken through exercises where 2-variable inequalities are graphed. You'll see examples and learn about solid line and dotted line graphs. The lessons will also cover systems of inequalities. You'll be presented with some sample problems that will allow you to try out what you have learned to ensure you are grasping the concepts.

Absolute value inequalities are another topic of discussion within these lessons. You'll learn how to use set notation when solving an absolute value inequality. When watching the lessons, you'll discover all the ins and outs of absolute value inequality. To be sure you really are getting it, practice problems are presented for practical work with absolute values.

Through the carefully explained lessons and real-world examples, the concepts are presented to you in a way that will stick with you. Even if you have struggled with understanding algebraic concepts in the past, these videos are ready to put things in simple terms that will help you to become skilled in inequalities.
