Number is an eloquent, approachable tour de force that traces the evolution of the concept of number from prehistoric origins to the twentieth century.

Tobias Dantzig, a well-known math professor, demonstrates that the evolution of math—from the invention of counting to the discovery of infinity—is a profoundly human story that evolved by “trying and erring, groping and stumbling.”

Professor Dantzig explains how improvements in arithmetic were spurred by commerce, war, and religion. He tells the stories of individuals whose innovations broadened the concept of number and gave birth to the mathematics we know today.
