A proposed pattern in prime-number endings
This short mathematics title centers on a formula the author says connects prime and composite numbers. Its stated focus is the final digits of prime numbers, with 2 and 5 set aside, and the author’s claim that the remaining primes have equal chances of ending in 1, 3, 7, or 9. The description presents this as the author’s discovery; it does not provide the formula or explain its derivation, so the book’s scope is framed more narrowly than a general introduction to number theory.
