Be a Wizard with Numbers: 101 Ways to Count Yourself Smart

by Andrew Jeffrey

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.

Topics superficially surveyed. Wizard I am not.

I love little books that show tricks with numbers. I want to read more about Ada Lovelace know that I know here tie to computer science.

Interesting little book, and full of interesting stuff, but it's the sort of book you zip through and then forget. Or at least I did....
