Description:

This text for a one-term course in elementary algebra is intended for students with a firm background in arithmetic. Problem solving and applications are emphasized. Coverage progresses from algebraic expressions and equations and inequalities to quadratic equations. New to this edition are sections on connecting concepts, study tips, and exercises designed to foster intuitive problem solving for particular types of problems. Other new material includes a "gentle" introduction to interpolation and extrapolation, and expanded material on rates and units. Bittinger teaches at Indiana University. Ellenbogen teaches at Community College of Vermont. c. Book News Inc.
