This book WON'T test your mental maths or teach you countless ways to find x. It WILL show you just how fascinating maths can be. Can maths make people rich? Can formulas predict which sports teams will win more games? Can equations explain the mysteries of the universe? The short answer to all these is YES. This book explores and explains the ways that the tools of mathematics help people make sense of the world around them, predict the future and, just maybe, how to make life itself better.
