圖書描述

Can you multiply and divide by 2 or 10 without pencil and paper? Of course you can. And believe it or not, with just those two skills and a few simple tricks you can perform just about any everyday calculation in your head That's just a small sample of the kind of number wizardry readers will learn to master in this amazingly entertaining and supremely practical book. The author--a former math teacher who wows audiences as "The Mathemagician"--takes the anxiety out of numbers for everyone from schoolkids suffering from math phobia to grown-ups bargaining for the best car deal. And he also provides the kind of intriguing mental exercises that keep aging brains flexible and fit.
