You can draw pretty pictures if you like, but they are something of a
dead-end. You really need some kind of formal axioms stated in the language
of formal logic and set theory, if your intention is rigorously prove things
about the natural numbers. As a starting point for number theory, there is
still none better than Peano's 5 simple axioms.

In the end the natural numbers is just named/symboled hashmarks that have
order, thus a sucessor and predecessor. But one only have sucessor.

Everything else is just anal excercises.

Not even a number 0

||=2
|||=3
||||=4
