Numbers and maths are all around us. They can explain where electricity comes from, why we look like our parents, why moons revolve around planets, and why it's so hard to win the lottery. We've Got Your Number investigates all aspects of mathematics and numbers and is arranged in a number of thematic chapters. Within each chapter is a series of self-contained spreads, each of which investigates all aspects of a specific subject, such as the different counting bases or the evolution of money.
