Designed for first-year developmental students who need support in intermediate algebra, the Fourth Edition of Intermediate Algebra 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 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.
