Sometimes this "What have you tried" thing seems silly.

Take this question [edit: question deleted/link broken] for example. It's obvious that one should try to do it by induction, but it's not the same as asking how to prove $\sum_1^n j=n(n+1)/2$, in that it's not obvious, or at least it wasn't obvious to me, how to make the proof by induction work.

Supposing that's so, what would "I tried to do it by induction but I don't see how" have added? I gather that that would make the question more acceptable, but I really don't get it.

Edit: I've been told that's a senseless question because the answer is obviously "that would have added nothing". It was a rhetorical question, sorry.

Next question: Fine. Then what specifically could the OP have said, about that question, regarding what he'd tried, in order to show he'd worked on it?

That's rhetorical as well, although much less so, certainly less obviously so. I can't imagine anything specific the OP could have said along those lines. Here's why: I did spend a few minutes "working" on the question. Wasn't going to give it a lot of time, but I did work on it, cuz it pissed me off, seemed like something I should be able to do. But during the time I was working on it it didn't happen once that I tried something that failed. It just wasn't that sort of difficulty - where I was stuck was thinking of something to try.

It's a fact that I did work on it, and it's a fact that if I hadn't seen the solution I'd be totally unable to give any evidence whatever that I'd worked on it.

My point, for those to whom it's not clear, carefully phrased as a question: Might it not be a good thing if before whining about "show your work" we stopped to consider that there is such a thing as working on a question without being able to produce evidence to that effect?

Supposing one agreed with that in principle, one could try to avoid asking unreasonable "what have you tried?" questions by making certain that before asking that one actually had at least a reasonable approach in mind. (In the question I'm talking about the guy who said "Try induction" more or less admitted when asked that he didn't see how to do it by induction. Suggesting induction as something that might work, fine, bbut suggesting as though it was clear it was something the OP should have tried but didn't, not fine unless we do see how it works.)

(So as to avoid answering questions from someone who really has no clue and hasn't even considered induction, I posted an answer which it seems to me should help only if the OP is thinking about induction...)

And, finally, I want to know how the OP thinks about the question and what methods they have at hand.

I have taken, recently, to broadening my meager repertoire of responses to context-free questions beyond a bare "What have you tried?" because, in essence, I agree: There are plenty of times when that question just doesn't seem sensible. The hardest task is occasionally just figuring out how to begin. Alternatives to WHYT that sound reasonable to me include:

  • What are you studying?
  • What text is this drawn from, if any? If not, how did the question arise?
  • What kind of approaches (to similar problems) are you familiar with?
  • What kind of answer are you looking for? Basic approach, hint, explanation, something else?
  • Is this question something you think you should be able to answer? Why or why not?

This list is not meant to be exhaustive, nor are all of them applicable to all questions, but I have found them useful options to keep in mind.

The underlying problem, in my opinion, is the conception that one of the primary goals of MSE is

Student arrives with an exercise and leaves with a solution.

In other words, one posts to MSE in order to outsource their mathematical exercises.

But this is (again in my opinion) an inappropriate use of the site! What we really want is something more like

Student asks a question about mathematics and learns something, and maybe others learn too!

It's fine if an exercise prompted the question, and it's great if the student's new knowledge allows them to solve their exercise and future exercises as well, but the important thing is that the point of the interaction is to learn something mathematical!

The point of WHYT (in my opinion) is that if questioners post enough about their knowledge and thought processes, that answerers can divine the questions that should have been asked — the questions about learning mathematics that the questioners need — and proceed to answer that.

In other words, WHYT is meant as an aide. Rather than close a question outright, it is an attempt to help the questioner transform a question that is inappropriate for MSE into one that is appropriate for MSE, or at least implies an appropriate question.

If the only thing a user will provide is an exercise, then the question is simply inappropriate for MSE.

    $\begingroup$ Incidentally, I share your dislike of WHYT, but for the opposite reason -- I don't think it's effective in its goal, and has the negative side effects of causing grief and perpetuating the conception that MSE is about arriving with exercises and leaving with solutions. But I'm out of touch with the current trends, so I can't claim confidently that its ineffective. $\endgroup$

In addition to the fact that we're not meant to do a person's homework for them, there's a more subtle reason to ask a question like that. Particularly for questions where the poster has just copied the homework question, it may not always be obvious what the context for the question is.

Typically, if you've got a homework question, you're supposed to apply something you've recently learned to solve it, but we don't know what class the poster is taking, let alone what material was most recently covered. The poster may be looking for something involving basic arithmetic but their question may also have solutions in Galois Theory, or Combinatorics, or Advanced Hypermathical Topomology, and it's not going to be helpful for the poster to offer the wrong one.


I'm a frequent answer-er and basic homework hint-er on Computer Science. Perhaps some outsider perspective is useful here.

Do note that we have chosen for a very different attitude wrt 'homework' than math.se, for a good reason, in my opinion.

Our way to help the 'clueless' is the following procedure:

  1. If it looks like a verbatim copy of homework, politely tell them they shouldn't just dump homework and expect us to solve it. Us solving their homework is unlikely to help them.
  2. If it seems they have done something but are stuck and merely state confusion, ask them to clarify.
  3. Okay, if it now is clear what the problem is an whether it is trivial, decide whether an answer or hint will help. Err on the side of hinting, answers will spoil the hints, but not the other way around. On CS, we usually hint in comments, as they aren't really answers.
  4. Finally, if it seems this now look like a serious question, answer it!

Ideally, questions start at 1 or 2 and step by step become 3 or 4 and remain there. This takes a bit of back and forth, but seems to work well. Some are really helped by 3 (i.e. the hint has helped them to solve the question by themselves!) or other times they had a real serious question that has merely been badly asked and lead to 4. All this can be done before closing the question on CS.SE, but perhaps this is unsustainable on a site of your size.

Of course, people often get stuck at 1 or 2, but it isn't hard to advance to 3 or 4. It merely means you have to take your question and SE seriously. If you cannot do that then, well, you are better of without us.
