Math through the ages

How did mathematics take shape, and who first devised the symbols of algebra? The book explores such questions through its origins, tracing the histories of negative numbers, the metric system, quadratic equations, and the sine and cosine functions.

It is made up of 25 self-contained vignettes that can be read in any order. Each one closes with questions and projects that help readers explore its subject further and connect it to the larger story. Reading suggestions at the end of each vignette point toward sources for anyone who wants to go deeper. The tone is relaxed and conversational, aimed at teachers, students, and general readers with an interest in how mathematical ideas developed.

The vignettes are preceded by a 56-page overview that sweeps across the whole history of mathematics, highlighting the key figures, events, and trends behind the mathematics used today.
