About This Chapter

The Inequalities chapter of this Holt McDougal Algebra I Companion Course helps students learn the essential lessons associated with inequalities. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Inequalities textbook chapter.

How It Works:

  • Identify the lessons in the Holt McDougal Inequalities chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the inequalities topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn to:

  • Convert mathematical sentences to inequalities
  • Write open or true and false statements
  • Graph inequalities with one and two variables
  • Add, subtract, multiply or divide with inequalities
  • Solve 1-step or multi-step inequalities
