comment A (non-artificial) example of a ring without maximal ideals
To make an answer like this more useful, you can include a description of what was proved in the paper. If the only content is a paper title, then the post could be a comment instead of an answer.

comment Proof of $a^n+b^n$ divisible by a+b when n is odd
I voted to put this on hold because it is unclear. Are $a$ and $b$ numbers, or polynomial variables?

comment Proof of $a^n+b^n$ divisible by a+b when n is odd
I do think that the use of $a$ and $b$ suggests that the question is about numerical division, rather than polynomial division. The OP should clarify this.

comment Is this Cayley table correctly computed? If so, is it correct way of presentation of this dihedral group?
This is not an answer to the question. At best, this should be a comment below the question.

comment Users providing only answers in Maple
I think that, unless the question explicitly asks how to compute something in a CAS, a mathematical answer to "How do I compute this" is not "Use Maple". However, the use of Maple might make a reasonable comment below the question, to add context to the question of how to perform the computation.

comment Users providing only answers in Maple
@Alex: you did the right thing by considering the content and coming to a decision whether to downvote and/or delete. I might have been more firm about deleting ones that give a Maple answer to a conceptual question. But the decision is up to you as a reviewer, in the end. Unfortunately, there are several users who post non-mathematical "answer only" posts, and there are users who vote up such posts, even though the answers are arguably not mathematical.
