## Summary

**Bob Blitze**r’s unique background in mathematics and behavioral sciences, along with his commitment to teaching, inspired him to develop a precalculus series that gets readers engaged and keeps them engaged. Presenting the full scope of the mathematics is just the first step. **Blitzer** draws in the reader with vivid applications that use math to solve real-life problems.

These applications help answer the question “When will I ever use this?” Readers stay engaged because the book helps them remain focused as they study. The three-step learning system–See It, Hear It, Try It–makes examples easy to follow, while frequent annotations offer the support and guidance of an instructor’s voice. Every page is interesting and relevant, ensuring that readers will actually use their textbook to achieve success! This textbook comes with two CD-ROMs.

Extensive exercise sets at the end of each section are organized into seven categories: Practice Exercises, PracticePlus Exercises, Application Exercises, Writing in Mathematics, Technology Exercises, Critical Thinking Exercises, and Preview Exercises. This variety lets instructors create well-rounded homework assignments, while holding students’ interest with an ongoing selection of novel applications. Integrated study aids help students make the most of their time outside of the classroom.

For all readers interested in college algebra.

## Author Biography

**Bob Blitzer** is a native of Manhattan and received a Bachelor of Arts degree with dual majors in mathematics and psychology (minor: English literature) from the City College of New York. His unusual combination of academic interests led him toward a Master of Arts in mathematics from the University of Miami and a doctorate in behavioral sciences from Nova University. Bob is most energized by teaching mathematics and has taught a variety of mathematics courses at Miami-Dade College for nearly 30 years. He has received numerous teaching awards, including Innovator of the Year from the League for Innovations in the Community College, and was among the first group of recipients at Miami-Dade College for an endowed chair based on excellence in the classroom. Bob has written *Intermediate Algebra for College Students, Introductory Algebra for College Students, Essentials of Intermediate Algebra for College Students, Introductory and Intermediate Algebra for College Students, Essentials of Introductory and Intermediate Algebra for College Students, Algebra for College Students, Thinking Mathematically, College Algebra, Algebra and Trigonometry*, and *Precalculus*, all published by Pearson Prentice Hall.
