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.
