Idea:Only primes are proper numbers – the rest are just constructed from primesLink:https://mashable.com/article/w...Primes are going to keep us busy for a long long time. Not sure if that is “proper” or not. But there you go.

Idea:Only primes are proper numbers – the rest are just constructed from primesLink:https://simple.wikipedia.org/w...INTERESTING, BUT… the fundamental theorem of arithmetic states: “The theorem says that every positive integer greater than 1 can be written as a product of prime numbers (or the integer is itself a prime number). … If two people found two different ways to write the number, the only thing that can be different is the order in which the primes are written.”
