Figuring: The Joy of Numbers

'There is a range and richness to numbers – they can come alive, cease to be symbols written on a black board, and lead the reader into a world of intellectual adventure where calculations are thrilling.'

In Figuring, Shakuntala Devi dramatizes the endless fascination of numbers and their ability to amaze and entertain. She offers easy-to-learn short cuts – how to add long columns in your head, multiply, divide, and find square roots quickly, almost magically. Fractions, decimals, and compound interest become clear and easy to deal with.

The author takes delight in working out huge problems mentally – sometimes even faster than computers. In Figuring, she shares her secrets with you.
