Overview

Students often struggle to find the relevance of math in their everyday lives. In Thinking Mathematically, 7th Edition, Robert Blitzer’s distinctive and relatable voice engages students in the world of math through compelling, real-world applications — student-loan debt, time breakdown for an average NFL broadcast, and many more.

Understanding that most students in this course are not math majors (and are unlikely to take another math class), Blitzer uses current data compiled from hundreds of books, magazines, and online sources to show students how truly meaningful and fun math can be.
