Regarding your question about keeping flawed answers: there are several reasons people delete their answers once a fundamental flaw has been pointed out: the question will not appear in the Unanswered queue if it has an upvoted incorrect answer, so deleting the flawed approach allows the question to receive more attention; the answer author may want to fix ...

Your question is well-received (4 net upvotes so far) on the main site. I would certainly consider it on-topic. It may be less accessible to users who don't have a physics background though. That said, if I were you, I would focus more on how to get a satisfactory answer to the question, instead of worrying too much about reasons why it has not received any ...

You ask: What should I do when I think that I understand and/or have an answer to an on-hold or closed - and, more specifically, "unclear" - question? You should help to make the question more clear, so that it can be reopened. To do so you can propose changes and improvements in comments. You can even propose edits directly. For larger changes this ...

The question you asked rather strikes me as "too broad", or as it is called now, it "needs more focus", as "[t]his question currently includes multiple questions in one. It should focus on one problem only." But, I suppose one can also paraphrase that as it needing "clarity." The site works best for relatively short, clear-cut problems. The site is not a ...

You simultaneously cross-posted the same question on both Math.SE and Math Educators.SE. That is not appropriate: cross-posting is generally considered not suitable on Stack Exchange. See Is cross-posting a question on multiple Stack Exchange sites permitted if the question is on-topic for each site?. This site is not intended for blog posts. You write ...

When asking these kinds of questions, it can be quite helpful to ask the converse as well: what's right with this question? What can't be improved? And when I look at your linked question I find myself unable to answer my own. First off: what's FOL? It seems to be an important part of your question but you haven't explained it. If one of your links ...

When you flag an answer as "not an answer" or "very low quality", the answer is pushed into the Low Quality review queue where other users can judge whether in their opinion your flag was justified. In this case, all three reviewers chose the "Looks OK" option, which resulted in your flag being "disputed". After that review, another user flagged the post as "...

This was linked from the closure notification. What topics can I ask about here? Mathematics Stack Exchange is for people studying mathematics at any level and professionals in related fields. We welcome questions about: Understanding mathematical concepts and theorems. Mathematical problems such as one might come across in a course or ...

I can't comment on the mathematics of your question because I don't know logic, but I can critique your writing. Is there something offensive in the style of my writing? I wouldn't say your writing is offensive, but you need to work on clarity and brevity. To me, the question reads a lot like a direct transcription of from your own notes, or even a ...

When someone points out that an answer of mine is wrong I usually delete it. But if it's wrong in an interesting or useful way I edit it to say so and leave it. Here's one example: Symmetry group of a cube: $O_h \cong O \times C_2$ . I don't know whether it was accepted before or after my edit.

I have awarded the bounty on the Question at issue, wishing that I could have done more than just upvote other Answers provided. One thing that in hindsight would have been helpful is an Edit to that Question that pins down where in Pugh's book that proof is found. There seem to have been more than one editions/revisions, so a more complete citation (e.g. ...

Relatively long question often do not fare so well. Especially if they are somewhat open-ended. The site works best for clear-cut and directly answerable questions. That said, I think actually "b" might play a role by now, and it would be best to steer clear of this. Study How to ask a good question. and maybe also How to grab users' attention ...

Mentioning the series is fine. Most people just mention the series, but the reason they get downvoted or closed is usually that their questions don't show effort, and so it gets flagged as missing context. Your question clearly shows effort, so it wouldn't be closed.

Every user with 10k+ reputation can vote to delete closed questions, and undelete deleted questions. There is essentially no restriction on that. Unlike close/open votes, the same users can cast delete/undelete votes as many times as they like on the same post. So it is not uncommon to see delete/undelete wars. I think most users believe that good content ...

A general advice on choice of tags: How am I supposed to use tags? I will repeat one advice given there - during and after posting the question you're shown several lists of similar questions. You could check some of those post, maybe looking at the tag used on other related posts will help you to find some other suitable tag. You could also try asking in ...

Please don't be "infuriated" by having a Question placed on hold. It is an invitation to improve the problem statement, not a personal criticism. While I did not review your Question, I can sympathize both with those who voted to close it and with you for having a genuine curiosity about the rules for order of precedence. Perhaps you can find a better way ...

NB: This is general advice, meant to address the question "What do I need to do in order to get my question reopened?" I have read the specific question mentioned in this topic, but I have not gone over it in detail, and have no intention of addressing that question specifically. What follows is advice which is meant to help any asker who finds ...

I posted about this bug on Meta Stack Exchange as well: Deleted posts still show up in search results (sometimes), since I encountered it on another site as well. A few days later, I got a response from one of the Community Managers, Shog9: As you suspected, undeleting and re-deleting the question removed it from the index. With the original deletion so far ...

I added the tag music-theory, which seemed fitting, and kept relations and discrete-mathematics, since those seemed like a reasonable choice. I removed complex-analysis, which seems not related; this tag is for the study of functions of complex numbers, and not about analyzing complex problems. I also removed elementary-set-theory as it does not seem ...

Let $m=2$, $r=3$, $n=4$; then the second equation says $${6\choose3}=\sum_0^3{2\choose k}{4\choose3-k}={2\choose0}{4\choose3}+{2\choose1}{4\choose2}+{2\choose2}{4\choose1}$$ Now let $m=2$, $r=1$, $n=4$; then the first equation says $${6\choose3}=\sum_0^2{2\choose k}{4\choose k+1}={2\choose0}{4\choose1}+{2\choose1}{4\choose2}+{2\choose2}{4\choose3}$$ These ...

Besides some inefficient use of MathJax or uninteresting view of your question, for those who are new to your question (even me in this case), some ambiguities may arise: What is a Miller type integrator? What do the variables in you question stand for? and which subfield of mathematics are you pursuing? As you said, a simple graph cannot be plotted since ...

I have found the post at Book on Lipschitz continuity. I post it as an answer to peacefully close this question.

Arbuja, glad to see you took out the language that was dismissive of your tutor and added a graceful acknowledgement for the help you got from WillieWong. I changed my down-vote to an up-vote, as those were the things that caused me to down-vote it. I hope you get more responses and input from this second post, and keep posting interesting questions. (I ...

You most likely have a strong intuition about doing mathematics in "formal grammars, formal languages, etc." that motivated your Question. But having gone through it twice, it seems a long way from being suitable content for Math.SE. Calling it "opinion based" may be the best peg to hang this Question on, but that is something of an ...

Yes and No. Keeping an incorrect answer prevents the asker from getting the correct answer as people won't see it in the unanswered queue, so for that reason alone the answer should be removed. However, there may be times in which a minor error in an answer once pointed out in comments or via an edit makes the answer good enough for the asker. Ultimately ...
