Numbers

To understand numbers, it is necessary to understand what they mean, how they work and how they may be manipulated. And there is no better way to study these things than by looking at the history of numbers. For it is in the past that it is easiest to see how our ancestors gradually discovered the properties of numbers, and gradually discovered and improved the techniques of making numbers work. When did men begin to count and record numbers? Just what is number? And how and why have people's ideas about that question changed over the ages? How many different methods have been invented, over the centuries, to perform each of the main arithmetical processes? Who made the first calculating machines? And when? And what could they calculate, and how? When did people hit on the idea of solving problems by equations? The answers, from ancient Greece to the present, can illuminate mathematical understanding and nurture numeracy. Anyone with an interest in numbers will find Graham Flegg's book invaluable for the exceptionally wide range of topics which it covers.
