The author of the question flagged and requested it be migrated to Computer Science. Although such questions are also on topic here, if the author requests migration, and the question is also on-topic on the requested target, I see no reason not to oblige.

Personally, I don't think the question is sexist towards women, or that the edit is sexist towards men. With that said, the fact that I'm not offended by it doesn't invalidate the feelings of the people who are. They have a right to feel that way. There are good points on either side. But it doesn't matter. The edit itself is a matter of taste, and ...

Although I am not endorsing Makoto Kato's deleted answer [added: in fact, perhaps it will help people to see the spirit of where I am coming from if I disclose that I downvoted that answer before it was deleted], I have to think that deleting an answer on meta -- which is essentially a forum for discussion of math.SE topics -- should be done only in rather ...

I can't understand at all why this question was closed. It is a perfectly sensible question in algebraic number theory. I have answered many questions of this kind before on MSE (some asked by the present OP, and some not), and one of the things I enjoy about MSE (which makes it different to, e.g., MO) is that it provides nice beginning graduate-level ...

Many aspects to this. I agree to a great extent with the points raised in the other answers. Yes, there are XY problems. Yes, the question is not here just for the benefit of the asker, and this shows in our expectations and also in the answers. I want to emphasize one aspect not present in the other answers. The actual mathematical problem underlying ...

There are two issues at play, here. This post deals with the way the post was edited, rather than the end state of the post. The Editor is an SE Representative Regardless of whether or not Jaydles was acting in an official manner, he represents StackExchange. As such, his action reflects on SE whether he intended it or not. This has a large intimidation ...

Apologies for the length of this post, but as one of the organizers of an external contest (the entrance quiz for the Canada/USA Mathcamp summer program) I want to add a bit of information to this discussion. Back in February, we were alerted by a math.SE user that someone had posted five of our entrance quiz questions to math.SE. The deadline was still a ...

Next time just flag the post for moderator attention. Site moderators can "lock" the post, which will prevent any and all further edits by normal users. It has already been temporarily locked once, and I have just put it in a longer lock. The user may give up after this, but if not the site moderators can take preventive measures against the user instead ...

I'd avoid the word 'best;' it just causes the problem of subjectivity and does not bring much precision in return. You search for references in a relatively specific subject. Explain in a bit more detail than you did already what it is about and what you have read already. Then, ask for additional references to further your studies in this direction. Try ...

Disclaimer: I hadn't seen your question before following the link in this meta question. I'm basing this answer on the first revision of the question. The title is the title, not the first sentence of the body. The question appeared to start (and still does) with a parenthentical sentence which is lacking context, and that's a bad first impression. This is ...

Now might be a good time to provide information that I do not think even the other moderators have. Some time ago I was contacted by David Savitt, who helps run Canada/USA Mathcamp, about an account that was posting questions from their entrance examination. More recently I was again contacted by David Savitt about several other accounts that he believed to ...

This question can be understood as Not a question, but a call for contributions to a project. Should be closed as "not a real question" (no longer a standard reason, but can be a custom off-topic reason). Is a many-in-one question: how do I solve $n$th problem in the book, for $n$ from $1$ to $N$? Should be closed as overly broad. A solution manual is a ...

Short answer: Your question is great! I wish more people asked questions like you. Long answer: Of course, anything can be improved. :P Let's address your specific concerns: How to title the question so that it can be relevant for someone apart from just me? Do I describe the problem as its given, along with unnecessary physical details? Do I describe ...

This is an unacceptable abuse of the site, as it is more-or-less equivalent to reposting the exact same question multiple times due to impatience. The course of action I would take in this event is to flag for moderator attention (they can attempt to communicate with the user and possibly enact penalties that apply to more than just the user account), ...

"Missing context" is a bit of a catch-all term, but basically it's a request for you to motivate the question (why do you want to solve this? Why is it interesting for you, and for people who might help you with it?) and to show some effort (there's a $\sqrt{2}$ there that suggests there's a substitution that might work -- what have you tried? Where did it ...

Note that the "you must show some prior work" maxim applies with greater force to homework questions, and even there it rarely leads to even blatantly violating questions being closed. Conversely, the rule applies less (i.e. not at all) to non-homework questions by non-mathematicians. There the asker is not supposed to know already how to start doing any ...

I did vote for closing with the following reasons: At first I think that this kind of question didn't really fit on this site, as it says in the faq, which questions can I ask here: Understanding mathematical concepts and theorems Hints on mathematical problems (but please read our FAQ about homework questions) History and development of ...

I hesitated to do so at first, but if everyone will remember that we're all in this together, I will give an example of what I was talking about in my comments. I had in mind this question, in which a PhD in computer science admits that he's never seen any applications of groups, rings or fields in his cs work and wonders whether such applications exist. I ...

A few comments: Yes, I personally agree with the commenter that this wasn't a great answer. You clearly have a lot of insight into the transpose operation that you wanted to convey, but unfortunately that insight isn't very helpful for understanding why $\det(A^T)=\det(A)$. It doesn't matter how insightful or well-written an answer is if it doesn't ...

As a preamble let me say that I consider questions touched upon here as important in general, yet the precise instance seems in any case minor in the general context of the problematic so that I think one should not get too upset about it either way. I do consider the (original) formulation of the puzzle as unfortunate, to no small extent for the starting ...

The question was automatically deleted by the Community♦ bot: Apr 11 at 0:16 history deleted Community♦ Scheduled: RemoveDeadQuestions It had a score of $-2$, was more than 30 days old, and had no answer. Such questions are automatically deleted network wide. Your question was never closed, old negatively scored questions without activity are ...

No one can speak for all of the downvoters on that question. Based on the upvotes to Phira's answer, I would speculate that many agree that the particular concerns you raised regarding \mbox and superfluous braces are not important concerns for users of this site. I downvoted in part because of the behavior demonstrated in reaction to Phira's answer. I ...

My own view is that this question should not have been made CW. It is a legitimate question, which has more or less a definitive answer (namely that such an expression is indeterminate without more information/precision as to what is meant). Edit by J.M.: considering the number of upvotes on this post, can there be a final decision by the mods on whether ...

The question was linked on Hackernews, which is a rather high-traffic site: http://news.ycombinator.com/item?id=4910406

My opinions on this: In general, deleting and re-posting anything, be it questions or answers, in order to get rid of the negative score is a big no-no. There's a reason that the system is designed so that one can change one's vote after the post has been edited. I am sad that not more people pay attention to this feature. In the specific cases (such as ...

The OP did leave a comment below the question with some motivation: by n=3 is IMO 1996shortlist. so I think General n have this . Do not know to have who has this information or Paper? artofproblemsolving.com/Forum/… – So, it seems this is a generalization of another problem from the International Math Olympiad. In the end, I think it's better to think ...

You have several options: You can do your own research based on the information gained, to check what is correct and what is not correct. You can ask the authors for further clarification, as recommended by Gerry Myerson. You can consider circumstantial evidence to infer which of the two is more credible (author's reputation or score, the amount of ...
