My perhaps overly obvious suggestion is that requests for proof verification should be limited to proof actually given in the Question statement. This was prompted by a recently re-opened Question, b …

Provided you connect your "approach" to an actual problem to be solved, Math.SE should treat your Question as on-topic ("Is my approach correct?). However note that the context is important. Readers …

I personally have never downvoted any questions, ... I took a look at your summary of voting (on your Activity page for the main site). It shows you have voted four times, two up votes and two d …

Here's my rule of thumb for being on-topic: Can this Question be resolved by reasoned mathematical argument? Your post (on main Math.SE) ends with the following words: So what am I doing wrong? Do …

I would say these tags continue to have value here at M.SE and are not "marginal". MathEd.SE is a beta site, and so far has less than a thousand Questions posted. Making a change to M.SE priorities …

As a matter of principle I consider such Questions on topic. In practice of course the OP will not have given their "proof" sufficient critical thought to merit the effort of a critique. Still, it's …

Rather than focus on what the OP of the Question could or should have done "better", I'd note your exchange with the OP, eventually including in one Comment: You're confused about something, but I …

First, while questions at all levels are welcome at Math.SE, this is not true of all SE communities, so don't over-generalize from the situation here. When contemplating a post you think is "very bas …

I revised the short wiki text (aka "usage guidance") for the calculator tag as follows: Questions regarding calculators being used to solve math problems. A clear statement of the math problem to be …

The OP asks: ...but how come that my questions are closed instead of answered or edited? Setting aside the matter of the question closed-as-duplicate, putting on-hold Questions that are not up t …

As the "question" here seems to beg the issue of appropriateness (repeatedly acknowledging an "ambition [that] ultimately leads outside of the StackExchange format"), let me try to be as constructive …

I think an Asker who posts a Question that articulately considers the interpretation of an exercise is doing something right! Many low quality Questions hinge on a misinterpretation (one example of t …

Requests for references to applied mathematics literature are on-topic here. That said, your interests may be so specialized that better chances of a well-crafted reply exist in another SE site. I'm …

Based on my experience, it is certainly acceptable to ask for someone to summarize a narrow portion of a paper, eg. the proof of a Lemma or the requirements of a construction, or to help you locate a …

It is desirable that Questions posted on Math.SE be fairly self-contained and definitively answerable in terms of reasoned mathematical argument. Naturally these goals are not always perfectly met, b …
