Pondering a Proof

[lord_carbo]

In the group of multiplication with real numbers, 1 is considered the identity element. Therefore for all n, n * 1 = n. Granted even that proof doesn't dig into why 1 is the identity element, but we're getting closer.

The word "axiomatic" is sometimes meant to mean, "taken for granted." Basically, we take axioms in math for granted. As far as 1 * 1 = 1 or anything like that, you don't need a proof. It's obvious. We can take it for granted.
