Common Sense Mathematics, 2nd Edition

What you’ll find inside

Common Sense Mathematics, 2nd Edition by Ethan D. Bolker and Maura B. Mast approaches quantitative reasoning through questions drawn from everyday life. Instead of organizing the whole book around abstract techniques, the authors use practical contexts to show how estimation, arithmetic, algebra, statistics and probability help people interpret information and make decisions.

Use mathematics to read real-world numbers

Early chapters cover estimation, units and conversion, percentages, sales tax, discounts and inflation. The book then explores averages, distributions, charts and statistics, followed by linear models, climate-related data, exponential growth, borrowing and saving, and probability. Later material considers how to interpret tests and evidence. Together these topics connect number sense with decisions about money, public information and claims encountered in daily life.

Learn through context and useful tools

The second edition updates examples and exercises while keeping the book’s emphasis on careful thinking about numerical information. Readers work with real data and everyday situations, using calculators, spreadsheets and online information to support analysis. This makes the text a fit for quantitative literacy or general-education courses where the goal is to interpret numbers thoughtfully, explain a result and choose a reasonable method for a practical question.
