"Your world is profoundly mathematical."

Bob Blitzer continues to support and inspire students with his engaging approach, making Precalculus beloved year after year by students and instructors alike. Blitzer's unique background in mathematics and behavioral science informs a wide range of applications, drawn from pop culture and up-to-date references, that appeal to students of all majors and connect math to students' lives. In the 7th Edition, relevant new applications topics include World Tiger Population, COVID-19 Pandemic, Area Burned by Wildfires in the U.S., Use of Social Media by Age and more.

Hallmark features of this title

  • Voice balloons translate algebraic ideas into everyday English, clarify procedures, present alternative ways of understanding concepts, and connect new concepts to practical applications.
  • Check Point Examples: Each example is followed by a similar matched problem called a Check Point, giving students a chance to test their understanding. 
  • Great Question! boxes present study tips in the context of students' questions and help alleviate anxiety about asking questions in the classroom. 
  • Graphing and Functions that model data appear in nearly every section and exercise set.
  • Brief Review boxes summarize the prerequisite mathematical skills students need to master the chapter's objectives.
  • Section Exercise Sets at the end of each section help reinforce the learnings from each section.

New and updated features of this title

  • Robert F. Blitzer's distinctive and relatable voice engages students in the world of math through compelling, real-world applications. Each section begins with a motivating hook that is continued through the section examples and exercises. Applications cover topics relevant to students, including many new to the 7th Edition:

About our author

Robert F. Blitzer is a native of Manhattan.  He received a Bachelor of Arts degree with dual majors in mathematics and psychology (and a minor in English literature) from the City College of New York. His unique 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's love for teaching mathematics was nourished for nearly 30 years at Miami Dade College, where he received numerous teaching awards, including Innovator of the Year from the League for Innovations in the Community College and an endowed chair based on excellence in the classroom. In addition to Precalculus, Bob has written textbooks covering developmental mathematics, introductory algebra, intermediate algebra, trigonometry, college algebra, algebra & trigonometry, and liberal arts mathematics, all published by Pearson. When not secluded in his Northern California writer's cabin, Bob can be found hiking the beaches and trails of Point Reyes National Seashore and tending to the chores required by his beloved entourage of horses, chickens, and irritable roosters.
