Tie your shoes faster than ever before, saving literally seconds of your life! Use those extra seconds to contemplate the diminishing returns of an exclamation-point at the end of every bullet-point! Make a working computer out of dominoes! Maths is a game. This book can be cut, drawn in, folded into shapes and will even take you to the fourth dimension.

Matt Parker, known as the Stand-up Mathematician, can be seen talking about maths on the BBC and at science fairs.
