Natural Numbers

If we had twelve fingers,
it would be much easier for us to understand
how the numbers are ordered.

 

 

introduction to theory of numbers

 

There are seven primary, separate, subsets of the set of Natural Numbers:

N = {2, 3, 5, 7} ∪ N2 ∪ N3 ∪ N5 ∪ N7 ∪ Pu ∪ (Pu x Pu)

Pu = (P ∪ {1}) \ {2, 3, 5, 7}
