A brief introduction to the prime numbers is followed by the solution to the hitherto unsolved problem of the pattern of the primes. This elusive pattern, so long hidden from view is here brought into the light. Other classic unsolved prime problems also have light shed on them too: Do Prime Twins like (29, 31) go on for ever? What about patterns like (11, 13, 17, 19)? The even number 30 is equal to 13+17 but can every even number be split into two primes like this? Goldbach's Conjecture was "Yes" but he failed to prove it and so has everyone else to date. Can a formula take a number, say 26, and give back 97 which is the 26th prime? This book explains how it can be done. A brief look at both Cryptography and the Factors of Numbers concludes the book.
