This edition marks the 23rd anniversary of the publication of this book. Since the First Edition, this book has helped thousands of liberal arts students experience mathematics rather than just "do problems," and become involved with the concepts rather than just "get the right answers." Now in the Eighth Edition, this text goes even farther in helping students master mathematics. An emphasis on problem solving and estimation, new problems coupled with numerous in-text study aids, and a student-friendly writing style give readers the confidence and ability to function in our technological world.
