Math in Society is a free, open textbook. This book is a survey of contemporary mathematical topics, most nonalgebraic, appropriate for a collegelevel 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 inclass, group, or individual investigation. This book is appropriate for Washington State Community Colleges' Math 107.
The current version is 2.6, released July 2022.

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 subeditions (like 2.1) with typo fixes but no major page/exercise number changes.
