In this richly entertaining and accessible book, Alex Bellos explodes the myth that maths is best left to the geeks. With wit and wisdom he unlocks the wonders of numbers for the curious reader, and peppers his text with narrative and incident to bring the history and mystery of maths to life. Bellos has a degree in Maths and Philosophy from Oxford, works for the "Guardian", has written an acclaimed book on Brazilian football and ghost-wrote Pele's autobiography.
