Numbers are such a big part of our lives, from when we wake up to when we go to bed, that we hardly even notice them. But how did humans start counting, and why? This book examines the history of an invention without which other inventions would never have existed. From the birth of numbers in Mesopotamia to the invention of zero, and the first calculating instruments and computers, this book unfolds the saga of numbers to reconcile even the most reluctant kids with mathematics!
