Math in Society

A survey of mathematics for the liberal arts major

Math in Society is a free, open textbook. This book is a survey of contemporary mathematical topics, most non-algebraic, appropriate for a college-level quantitative literacy topics course for liberal arts majors. The text is designed so that most chapters are independent, allowing the instructor to choose a selection of topics to be covered. Emphasis is placed on the applicability of the mathematics. Core material for each topic is covered in the main text, with additional depth available through exploration exercises appropriate for in-class, group, or individual investigation. This book is appropriate for Washington State Community Colleges' Math 107.

The current version is 2.6, released July 2022.

This text is intended to be a growing, collaborative work. Contributions of additional chapters, exercises, and extended projects or investigations are welcome. Please email the maintainer with any contributions.

In the past, I had individually editioned each chapter. Beginning with the second edition of the book, I will now be changing the edition of the whole book at once when changes are made. There will likely be sub-editions (like 2.1) with typo fixes but no major page/exercise number changes.

Creation of this text was supported, in part, by the Transition Math Project and the Open Course Library.
