MATHEMAGICS shows you how to add, subtract, multiply, and divide faster in your head than with a calculator, let alone using pencil and paper. Imagine knowing the cash register total at the supermarket before the clerk rings it up, or the exact tip at a restaurant without appearing to think about it. With MATHEMAGICS these tricks are so easy to learn that they make calculating actually enjoyable.
