Why do users give answers using alternative method when I'm asking what went wrong with my solution?

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 ...

Why do users give answers using alternative method when I'm asking what went wrong with my solution?

Not the exact answer to your situation, but it might give some idea, so in that sense, this answer is also an alternative answer to the question that you are asking. We are not your tutor in here, ...

Answering "is my approach correct" with a different proof

Your first example is structured like this: [mathematical statement] Is this statement true or false and why? [attempt at proof] Is this way of looking at it right or not? It is entirely fair to ...

Should I post my attempt as an answer or include it in the question

I don't think it's a good idea to post your attempt at an answer. If you're not sure about it, then it is more a part of the question. If you figure it out after asking, though, go ahead and post your ...

Should answering that someone's attempt is correct be posted as a comment?

As detailed elsewhere (see How to answer proof-verification questions?) I do not consider it as best practice to post only "this is correct" as an answer. Usually, something more can be said to make ...

Is it okay if I use this site to have someone check my work or give a solution?

It seems that there are two separate issues in what you are asking. So let me address them separately: Is it okay if I use this site to have someone check my work? This was discussed here on meta ...

Best way of asking "check my proof" questions

The best way to ask check-my-proof questions is not to simply ask users to check your proof. In what follows I've been strongly influenced by Raphael's answer on meta.cs.SE, and somewhat echo Qiaochu ...

Is my solution correct? Posts

When I first started studying rigorous mathematics I couldn't tell a proof from a carrot. I wasn't in a formal educational institution at the time and relied heavily on feedback from mentors in my ...

Proof verification types of questions

It really depends on where you are in learning mathematics. If you're at the stage where you can look at a proof and be confident about whether it is correct, then asking such questions is not likely ...

What is the protocol for telling others you have found your mistake in your working?

If you haven't yet received an answer, answer it yourself. That way, no one will add an answer which merely expresses what you'd already discovered yourself (which would be a waste of time) and your ...

Can I post questions to ask where I am making a mistake?

Interesting that each of the responses so far, to the posting, have assumed that the OP (i.e. original poster) should take specific actions. To me this ignores the real problem which is that there is ...

"Prove that" vs. "Confirmation of proof" in the title.

In my opinion, no, you do not need to say in the title that it is a proof-verification --- in fact, you do not even need to say that it is a proof. Phrases such as "Prove that", "Proving that", "How ...

How should questions tagged "solution-verification" be answered?

It's a good question, and one I have no universal response to. I dislike the flat "Yes, that's correct" response though I have used it. It's effectively meaningless. At best it is Proof by ...

Ask for proof verification and ask for other ways to prove the same statement. One or two questions?

I would advice you to put it in one question. You should tag it as proof-verfication and as alternative-proof, along with other tags regarding the field of the question. If you will have two ...

Are "Verify if I'm correct" questions really on-topic?

What is the usefulness of having "proof-verification" and "solution-verification" as different tags?

While there could be some meaningful distinction (in theory) this does not seem to work well in practice. I checked a bit manually, and also observed that 150 questions (this are almost 20 percent) of ...
