Common Sense Mathematics is a textbook designed for a one-semester, college-level course in quantitative literacy. It draws on examples from current events and the media to promote common sense, estimation, straightforward mathematics, and accessible software as tools for analyzing practical questions. The topics are organized around their underlying motivations, introducing students to mathematical ideas through real-world contexts. Percentages highlight the distinction between absolute and relative change. Linear functions model utility bills and taxes, while linear regression sheds light on climate change. Exponential functions are used to understand epidemic spread and car loan payments. Probability helps explain state lotteries, insurance, and sports betting. Additional chapters on unit conversions, inflation, and income distribution help students become informed consumers of numerical information. The second edition of Common Sense Mathematics received the 2022 Daniel Solow Author's Award from the Mathematical Association of America. New to the Third Edition: Estimation and visual data with charts, graphs, and current data Revised personal finance chapter with practical exercises and web resources Open-ended exercises focused on reasoning, trends, and real-world events Full-color examples, updated exercises, and a refreshed instructor guide An instructor's guide, solutions manual, and additional teaching materials are available at www.ams.org/publications/authors/books/postpub/text-76.
