For courses in Precalculus. This text takes the same approach as the regular Blitzer Precalculus version, but has been condensed by deleting the last 5 chapters (Chapter 7 Systems of Equations and Inequalities; Chapter 8 Matrices and Determinants; Chapter 9 Conic Sections and Analytic Geometry; Chapter 10 Sequences, Induction, and Probability; Chapter 11 Introduction to Calculus). This text explores math the way it evolved: by describing real problems and how math explains them. It is interesting, lively (with applications you won't see in any other math book), and exceedingly clear. Blitzer's philosophy: present the full scope of mathematics, while always (1) engaging the student by opening their minds to learning (2) keeping the student engaged on every page (3) explaining ideas directly, simply, and clearly. Students are strongly supported by a consistent pedagogical framework. A "See it, Hear it, Try it?" format consistently walks students through each and every example in just the same way that an instructor would teach this example in class. Blitzer liberally inserts voice balloons and annotations throughout the text helping clarify the more difficult concepts for students.
