This fifth edition of an algebra text has a new open format and expanded graphics which enforce concepts. Through an informal, active writing style and the use of numerous pedagogical aids, such as examples with matched problems, annotations, think boxes, chapter summaries and cumulative reviews, the text guides students of varied mathematical backgrounds to a point where they can profitably begin a study of applied calculus, computer science and statistics, and certain technical courses. There is a balanced presentation of theory, computational skills, and applications which exposes the student to a thorough understanding of the mathematics, its concepts, skills and use. Responding to the increasing popularity of graphing calculators in mathematics courses, numerous exercises that exploit the capabilities of these calculators have been added to this edition. Other new features include many illustrative examples, new and varied problems, and new and updated applications.
