Clearly written and comprehensive, the seventh edition of Gustafson and Frisk's popular book provides in-depth and precise coverage that is incorporated into a framework of tested teaching strategy. Gustafson and Frisk, both career mathematics educators, combine carefully selected pedagogical features and patient explanation to give students a book that preserves the integrity of mathematics, yet does not discourage them with material that is confusing or too rigorous. Long respected for its ability to help students quickly master difficult problems, this book also helps them develop the skills they'll need in future courses and in everyday life.
