A hilarious and bestselling reintroduction to mathematics, illustrating the ideas with stories, humor, and stick figures. In Math with Bad Drawings, Ben Orlin reveals what math is all about. His tools are unorthodox: jokes, cartoons, strange-but-true stories, and beneath it all, the empathy of a veteran teacher who believes that math should belong to everyone. Orlin helps us to think like mathematicians by teaching a brand-new game of tic-tac-toe, profiling the ten people you meet in line for the lottery, and documenting the headaches that ensue when the Evil Empire attempts to build a spherical Death Star. Math with Bad Drawings will change the way you see the subject—and the world.
