Yes. That is possible, and it certainly happens. This is why you should usually be critical and vote after reading and understanding an answer. And yes, sometimes people will vote a wrong answer because they trust the user. But hopefully someone will actually read it, and point out the mistakes. At least on my end as a high reputation user, that worked out ...

People are downvoting your answer because the question called for a proof and you posted a picture. While it is a nice illustration of the concept, it is inadequate on its own. You might improve your post by adding algebraic details showing how your idea is correct.

No, it's not against the Code of Conduct. Voting to close and offering suggestions to improve a question are not mutually exclusive. It is not unwelcoming to close an unclear question for being unclear, and while it is admirable and recommended to leave comments helping the OP to fix it, it is not mandatory. As to whether it is okay to vote to close based ...

The organization of the moderators team is informal. There is no hierarchy and there are no assigned roles. Of course, a less experienced moderators might ask more experienced ones for advice at times. There is no separate reputation-system either; in principle, there is statistical data on our activity. While this is not formalized, in practice there is a ...

I think it's reasonable to flip the direction of the synonym in this case for the sake of maintaining symmetry, i.e. keeping [differentiation] and [integration] as the master tags, rather than [derivatives] and [integration]. However, I disagree with the other reasons provided, namely that "derivatives" could refer to other things, i.e., "...

The StackOverflow blog post containing details on the introduction of these badges, is here. As the writer Jon says, These badges reward reversing the score of a negative question by answering it in a way that sheds new, positive light on the question, raising its score. It’s an answer so good it makes the question look good by association! I just had a ...

What is reputation? Reputation is a rough measurement of how much the community trusts you; it is earned by convincing your peers that you know what you’re talking about. Knowing much about mathematics does not equate with knowing much about Mathematics Stack Exchange. Of course, these are not mutually exclusive, but they're two different things and we don'...

This is a temporal coincidence. Comment deletions have no reputation impact. (And your comment wasn't near bad enough to get you into trouble, it was just on the "delete" side of the "what to do when flagged" question.) It just happened that in the same minute that your comment was deleted, also a question you had answered was deleted, ...

There are two questions wrapped up in this post: "What's wrong with my answer?", and "Explain downvoting behavior.". AlexanderGruber addresss the first question, so I'm going to respond to the second. At least let me know is anything wrong in the solution so that I can correct it. ... I don't mind even the post gets deleted but there ...

I'd like to tackle the second part of your Question: If so, how we can trust that answer if nobody up-vote it? The ideal for Math.SE is to have problems solved by reasoned mathematical argument. By this I mean the correctness of the solution should be evident by following the logic (reasoning) of the Answer. In particular we should avoid asking Readers ...

Reopened Annuity immediate and present value I disagree with the reason for closure. There is clear context in the form of a nearly complete (but ultimately incorrect) attempt to answer the question. The only possible reason I can think of that it might have been flagged for closure is that those who voted to close are unaware of the terminology used in ...

For what it's worth, sometimes new users will use the title as a "stand-alone" problem statement and then use the body of the Question to editorialize. In such cases I often leave a Comment asking them to use the additional space afforded by the body text to give a full presentation (setup and goal) of the problem they want help with, and to ...

I have a lot of answers out there and find this behavior quite rare-a few times a year. More often I get tagged after answering a recent question asking me to take a look at another of the same poster's questions, but that is still rare. I would agree it is rude, but say it is not a problem due to the rarity.

3

Yes, this is rude, really regardless of whether the post is old. If it is in a subject that they are interested in, they will see the new question and answer it if they want to. They don't need a notification to find these questions, it is likely they already visit MSE regularly and have watched tags to find questions they are interested in.

I think the status quo is fine. Linear systems of equations can belong in either algebra-precalculus or linear-algebra, depending on the techniques and tools the student knows and is expected to use. A linear-equations tag would probably draw traffic from the whole spectrum (not only about $2x+8=12$ but also about how to solve large sparse systems when the ...

Reopened Please reopen: Given $\sinh x$, find the exact value of $\cosh x, \cos 2x$ and $\tan 2x$. As the question stands now, there is evidence of clear and informative context, and through this, the OP has managed to answer their own question. The reasons for closing this question stem from when the question was in a worse state, but after the edits, ...
