It may look like magic, but it's really math! These tricks are as much fun as anything a magician pulls out of a hat-and lots easier to do. With just a pencil, paper, and a calculator, you can read minds, guess ages, make predictions, show off your amazing memory, and more. Plus it provides suggestions for an opening talk to set up your audience, and explanations for how each trick works. 96 pages, 40 b/w illus., 5 3/8 X 8 1/4.
