I'm a programmer learning maths on the side while working. I find one of the best ways to learn is to try and come up with my own proofs from first principles. I suppose these will either a) be wrong or b) be a variant of some existing (possibly canonical) proof.
For example, I wrote a proof of the "uniqueness" of the reals, which is probably a super basic subject to a lot of people here and has canonical proofs. The reason I'd like to post mine is that I've got a niggling feeling that I'm missing some details and/or making unwarranted assumptions. But effectively it would amount to posting my proof and asking whether it's correct.
Is this appropriate on math.stackexchange? I searched the meta forum but I couldn't find an unambiguous answer.
