In MATH WITH BAD DRAWINGS, Ben Orlin answers math's three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that math should belong to everyone.

Eschewing the tired old curriculum that begins in the wading pool of addition and subtraction and progresses to the shark infested waters of calculus (AKA the Great Weed Out Course), Orlin instead shows us how to think like a mathematician by teaching us a new game of Tic-Tac-Toe, how to understand an economic crisis by rolling a pair of dice, and the mathematical reason why you should never buy a second lottery ticket.

Every example in the book is illustrated with his trademark bad drawings, which convey both his humor and his message with perfect pitch and clarity. Organized by unconventional but compelling topics such as Statistics: The Fine Art of Honest Lying, Design: The Geometry of Stuff That Works, and Probability: The Mathematics of Maybe, MATH WITH BAD DRAWINGS is a perfect read for fans of illustrated popular science.
