Understanding Algebra for College Students - Tapa dura

The author aim to develop students' understanding of algebra concepts by using a spiral approach. This approach presents a topic at an elementary level and then returns to it at increasing levels of complexity. This gradual introduction builds student confidence while developing concepts, rules, and definitions. To complement this approach, the authors include numerical and algebraic examples that reflect a wide variety of situations. These illustrative examples compare and contrast related ideas, helping students understand the sometimes subtle distinctions among various situations.
