Helping students grasp the "why" of algebra through patient explanations, Hirsch and Goodman gradually build students' confidence without sacrificing rigor. To help student move beyond the "how" of algebra (computational proficiency) to the "why" (conceptual understanding), the authors introduce topics at an elementary level and return to them at increasing levels of complexity. Their gradual introduction of concepts, rules, and definitions through a wealth of illustrative examples - both numerical and algebraic-helps students compare contrast related ideas and understand the sometimes subtle distinctions among a variety of situations. The authors emphasize problem analysis and model building. For example, new sections help students identify and develop useful strategies for recognizing mathematical relationships as a first step in the process of solving applications.
I found this book this book to be one of the best designed mathematical textbooks that I’ve come across in my painfully long educational career. Hirsch not only takes the time to format the book so as to accentuate the most vital concepts of intermediate algebra, but he also gives you scores of detailed worked-out examples to ensure that the concepts find a purposeful application. I strongly recommend it as a great book to be used as a do-it-yourself guide through college algebra.
