This is a well-written exposition of some aspects of number theory. The prerequisites are just a knowledge of elementary arithmetic. Explanations are extremely lucid. Many of the topics chosen relate to prime numbers, including the frequency of prime numbers, a subject of continuing exploration by experts. Other chapters include an introduction to some aspects of the Fibonacci numbers, and a chapter on Diophantine equations - equations with whole number solutions. This book is a gentle introduction to some fascinating aspects of maths, and is a gem.
This book was brilliantly written, relying on some anecdotal stories to maintain interest before explaining the maths behind it. It assumed no previous knowledge of number theory, and was a wonderful read.
