Think of a Number is a maths book unlike any you've seen before. Most maths books teach you how to do sums and calculations, but Think of a Number is completely different.
This book is all about the weird and wonderful side of maths, with the hard bits left out. Find out why there are 60 minutes in an hour, why daisies have to have 34, 55, or 89 petals, and why finding a prime number could make you a millionaire.
Think of a Number is not just a reference book. It's also packed with activities that children can try out on their own or with friends, including brainteasers, magic tricks, and things to make. They can also learn about the simple puzzles that stumped the world's brainiest mathematicians for centuries.
