Forget about the calculator; this book will teach you how to quickly calculate in your head or with a pencil. To count faster, you just need to think a little differently, says author Yngve Vogt, a Norwegian journalist for the science magazine Apollon and a math enthusiast.

You'll learn simple and fun methods for speedy counting that only require a basic knowledge of arithmetic rules. The Trachtenberg method, the Chinese method of counting with dashes, and many other mathematical techniques will help you effortlessly add and subtract, multiply and divide, extract square roots, and square large numbers.

You'll also discover unusual facts and fascinating stories about numbers and the people who are obsessed with them, and discover a brief, thousand-year history of number systems, from Ancient Greece to today's digital age.
