Understanding Intermediate Algebra: a course for college students

The Story

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.
