Seems like you proved it by first assuming its true, then stating it was true. Doesn't quite work out to be a proof at that point.

Say we have a set A, and the operators on the set are + and * but the identity is the same for both. Then for any a in the A and the identity e, a+e=a and a*e=a. Are t...

I'm curious if there is a set-like collection of objects who's only difference from a set is that it allows for repeat elements. So like a set, order does not matter, but unlike a set repeat elements are allowed.
