• Skills Check problems precede the exercise sets, allowing students to quickly check if they have read and understood all the concepts needed to complete their homework.
• Exercise sets are designed to test student comprehension by incorporating the algebraic skills covered in the Skills Check with the application problems they will encounter in the real world.
• Chapter review material includes a wealth of resources to help students study efficiently.
• A chapter summary and grid outline Key Concepts and Formulas, which are organized by section and point back to the Key Concepts list at the beginning of each section.
• Skills Check problems and the exercise sets test students’ comprehension of the material in the chapter.
• The Note-Taking Guide provides a framework for students as they take notes for this course. Students have a guide to help them organize definitions, examples, and processes. The guide is available for download in MyLab Math and also as a print supplement.
