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.

There are more than 4,100 carefully selected and graded problems that are divided into A-, B-, and C- levels of difficulty in each exercise set. Exercise sets are found at the end of all sections.
There are a sufficient variety and number of applications in the text to convince even the most skeptical students that mathematics really is useful in everyday life. Found at the end of many exercise sets
Each concept is illustrated with one or more examples and following each example is a parallel problem with an answer.
Explore-Discuss Boxes/Group Activity: These boxes are interspersed at appropriate places to encourage a student to think about a relationship or process before a result is stated or to investigate additional consequences of a development in the text. This material can also be used as an in-class or out-of-class group activity. An additional group activity is located at the end of every chapter before the chapter review.
The text includes a wide variety of precalculus topics arranged so that many of the chapters after the third are independent of one another. The depth and completeness of coverage of most topics exceeds that found in most competing texts.
