Developed to prepare students in the combined elementary and intermediate algebra course for a college-level curriculum, Elementary and Intermediate Algebra, 4/e, retains the hallmark features for which the Larson team is known: abundant, high-quality applications; the use of real data; the integration of visualization (figures and graphs) throughout; and extensive opportunities for self-assessment (mid-chapter quizzes, review exercises, tests, and cumulative tests). In developing supportive new features for the Fourth Edition, the authors' goal is for students to come away from the class with a firm understanding of algebra and how it functions as a modern modeling language. What You Should Learn orients students to each section by listing the main objectives. Why You Should Learn It provides a motivational explanation for learning the given objectives. What Did You Learn? following each chapter highlights key mathematical terms and concepts. For easy reference, Key Terms are correlated to the chapter by page number, while Key Concepts are correlated by section number. Integrated Review Exercises appear before section exercises in every section. They offer a review of skills, definitions, and problem solving from previous chapters. Eduspace, powered by Blackboard, for the Larson/Hostetler Elementary and Intermediate Algebra course features algorithmic exercises, test bank content in question pools, an online study guide, interactive tutorials for appropriate sections and video explanations.
