# Ch 11: High School Algebra: Working With Inequalities

Watch online video lessons and learn about the different aspects of working with inequalities. Test your knowledge of inequalities with the self-assessment quizzes that follow each lesson.

## Working with Inequalities - Chapter Summary and Learning Objectives

Inequalities are simplified equations that use greater-than or less-than signs instead of a definitive equals sign and result in more than one answer. Our instructors show you the different types of inequalities and how they are graphed. Some lessons have a supplementary lesson that provides practice questions to hone your skills when working with inequalities. Additional topics covered during this chapter include how to:

• Express inequalities through compound inequalities, set notations and systems of inequalities
• Identify the differences between 1- and 2-variable inequalities
• Explain what the golden rule is for solving 1-variable absolute value inequalities
• Construct inequalities by translating number sentences
• Differentiate between OR and AND compound inequalities
