About the first part of your question (about low effort posts) - this is exactly what the "missing context" close reason is for. See also: New changes to close reasons. You can find some other related links in the corresponding tag-info. For the second part about standard posts, you can check the posts on the main which are tagged faq and also the ...

I saw this Meta question of yours, and happen to be the second undelete-voter. Let me explain why I voted to undelete. I did not see any indication that your answer was flawed, and I supposed that you would have stated it somewhere if it was. From what you say here, it seems that my guess is correct. Thus I think it is better to leave your answer undeleted. ...

If a question gets undeleted, the user who posted gets no notification about that undeletion. But you also get no notification if an answer of yours gets deleted. The only thing that happens (as you were told in the comments) is that that deletion or undeletion may cause a change in your reputation. Whether a user should get a notification under those ...

to the remark ...Right now, each user gets reputation for answering/editing questions... the editing of answers by anyone other than the poster should not be allowed for obvious reasons and it just hapenned to me in the last few hours by 2 different persons as i posted. For example i wrote matrix A and he comes back and edits where i wrote i he writes I and ...

I have edited the tag wiki to include the $_p F _q$ case and gave a mention to several extensions, as hardmath suggested. Please feel free to improve the blurb.

Had the same problem before as well and I too made a similar meta post over here. What I understood is that most of the stack exchange wants the site to become a 'give help-get help' site with its reputation system rather than be a site which is a knowledge repository/ a treasury of mathematical ideas. This is not a bad thing, you just have to use it the way ...

I don't think sharing the experience between fast low quality answers is a solution. In fact, it further encourages people to post fast, low-quality answers to low-quality questions. I think a better solution is for more people to vote quickly to close the question if it is a simple problem statement, and downvote any and all low-quality answers that appear. ...

The fact that your question was written to be answered by yourself is a red herring here, and has nothing to do with the reception of your question. The first thing you should be asking yourself is "Is my question a good question, per the site guidelines?" My first impression of the linked question—even in the current state—is that it doesn't ...

Ok, here is a proposition how this problem could get changed. Feel free to comment and give feedback on how you would see such a change: Right now, each user gets reputation for answering/editing questions and you get badges for special achievements like having good answering scores for a specific tag. I propose to combine these two systems: For each tag ...

It depends how you ask it. This is true of every type of question*, but it is easy to forget about when asking for a book recommendation. Simply asking "what is the best book to learn algebra from?" is a bad question (high school algebra, or abstract algebra? Also, any answer will be opinion-based, due to the word "best"). Asking "I'...

While there is no technical limitation to reviewing when you cannot take the entire range of possible actions, I think that it is not within the spirit of the review queues to review when you can't take action. Often, the right action is to up/downvote a question, or vote to close. If you cannot takes one of those actions, but those actions are possible ...

Personally, I disagree with the premise of this question. Sometimes when reviewing a first post or a late answer, the proper response is to vote up or down, which can't be done if you've maxed out votes. If you would risk doing the job improperly, wait a few hours and do it right, especially since the stakes are so low and for those two queues there are ...

Your profile shows you've voted 40 times today, which means you have no votes left. Since voting (up or down) is one of the most important things to do in the First Posts and Late Answers queues, you cannot review if you're out of votes.

I'll respond on the premise that you are taking issue with how Answers get framed on the main site (rather than with the Comments that get directed at what some consider "do my homework" posts, though I'm inclined to focus on whether the asker has digested the meaning of their problem, not whether it is any known sense "homework"). Some ...

Create the tag: hausdorff-spaces and make it a synonym of separation-axioms. Right now the tag separation-axioms is not quite used: for example, there seems to be over 3k questions about Hausdorff spaces that is not tagged separation-axioms. And for me, the term "separation" is not the first thing that comes to my mind.

If you want real Fitch-style, you could use: $\def\fitch#1#2{\begin{array}{|l}#1 \\ \hline #2\end{array}}$ $\def\fitch#1#2{\begin{array}{|l}#1 \\ \hline #2\end{array}}$ This can be nested: $\fitch{¬B ∧ (A⇒B)}{ A⇒B \\ ¬B\\ \fitch{A}{ B \\ ¬B \\ ⊥ \\ } \\ ¬A }$ Output is beautiful! $\fitch{¬B ∧ (A⇒B)}{ A⇒B \\ ¬B\\ \fitch{A}{ B \\ ¬...

You can't nest align environments but you can nest arrays (apparently, this requires $$...$$). Why would you bother? Because you can recreate the vertical line. Partial copy of the example of Luiz Martins: $%PREAMBLE \newcommand{\FITCH}[1]{\begin{array}{rlr}#1\end{array}} \newcommand{\FC}[1]{\begin{array}{r}#1\end{array}} %FirstColumn \newcommand{\SC}[1]{\...

Do be aware that even if you have a precise mathematical definition that you think captures (the non-mathematical) meritocracy, and you have rigorous mathematical proofs of certain theorems of this mathematical concept, there still is a disconnect between the mathematical theorems and the real-world concept. One will always need some non-mathematical ...

Another option is to use the align environment \begin{align*}...\end{align*}, rather than the array environment. This environment has more flexibility with spacing, which is useful if you don't want your output to look like a table (although this doesn't seem relevant to your example). The align environment gives an essentially identical output to array here:...

Yes it is. You can do it with MathJax's {array}. If you write \begin{array}{} aaaa \\ bb \\ cccccc \\ \end{array}, you'll get: $$\begin{array}{} aaaa \\ bb \\ cccccc \\ \end{array}$$ Notice that it's left justified. If you however add an 'r' inside the empty brackets, as in \begin{array}{r} aaaa \\ bb \\ cccccc \\ \end{array}, you'll get: $$\begin{array}{r} ...

Much of your question is answered by this blog post from 2019: https://stackoverflow.blog/2019/06/18/adios-to-unfriendly-badges-ahoy-lifejacket-and-lifeboat/ I believe, but am not completely sure, that badges are network-wide and not site-specific, so it's not possible to retire Precognitive, for example, because then sites that are in beta at the moment ...

I think several of your edits were useful and should have been approved. I think edits that add more information about the source of the problem are useful -- especially the edits of yours that added the exercise number. We are building an archive of questions and answers that hopefully will be useful to others in the future, and part of that is helping ...

I accepted the first edit suggested by you concerning Bartle's Introduction to Real Analysis, but then I started to notice that there were several of them. I found them weird. Why to edit the question this way years after the question was posted? Why to do it only about one specific textbook? What sense does it make to add the specific page of the textbook, ...

Your original question's answer and its comment train seems to have been cleaned up, so I can't say anything about them, but I can tell you that This meta post does come off as the work of someone who is new to math.se, and does not have much experience with interacting with the community here, which spans a wide range of English language ability, ...

The comment history on the answer doesn't exactly look good for anyone involved in the discussion. I might suggest, when you feel a little calmer, that you flag it for moderator attention and ask them to delete all the comments -- they certainly add nothing to the discussion. I can understand your frustration that the "answer" written was ...

If it is a private matter, which is essentially equivalent to it being reporting what you perceive as problematic behaviour of someone, then flag. If it is not a private matter, use the Math's mod office. Just to reiterate what was said here: Do not use e-mail. Regarding the specific flag you mention, it doesn't seem to be private. So use the Math's mod ...

Please do not post the same question on multiple sites. See the general rules on Meta.SE: Is cross-posting a question on multiple Stack Exchange sites permitted if the question is on-topic for each site?. These rules are the default for Stack Exchange sites. Individual SE sites can set a local policy that overrides that default, if they wish. If both ...

Proposal: Create tag xor xor, also known as symmetric difference, is a logical operator for which we have no separate name in English -- for example, when we say "do you want ice cream, or do you want cake", we mean xor but we say or. Since for many people, this is the first new logical operator they learn (since they already understand and, or, ...
