Proposal: Math Challenges
Homework questions are boon and bane at Math.SE
How will MatCh.SE deal with hw?
Will it be as stigmatized here as it is there?
As MathCh.SE is for users to challenge other users, isn't it supposed/required that the solution to a question is already known to the asker? If so, then aren't homework and contest questions just inherently off-topic?
It's possible I'm misinterpreting the purpose of the site, so the answers to the above could be "no". That said, Math.SE and MathOverflow already exist to address math questions whose answers are unknown to the asker; why bother adding a third site?
This raises the question:
How does the reader know that the solution is known to the asker?
I'm not sure. (I'm also not sure it matters. Does Puzzling.SE make a big deal about stuff like this?) Perhaps most issues and misunderstandings in this regard could be avoided with a clear notice in the question-entering form that knowledge of a solution is expected; a pointer to Math.SE as the place to post unsolved challenges (and/or to get homework assistance) would help, too. Of course, there are always after-the-fact consequences: downvotes from users and/or reprimands from moderators.
A final thought: If knowledge of a solution isn't expected of askers, then tags "solution-known" and "solution-unknown" would be helpful to readers. (Maybe each challenge should be required to show one tag or the other.)
Most homework questions are pretty routine and standard (if one knows the subject). I'd assume that most homework questions would be off-topic as not interesting, not creative, not challenging enough.
To get the details of this right is likely a difficult task, but I'm pretty sure that to work, this site needs to work-out and enforce some quality standards for the challenges.
These would run along lines quite different than on the Mathematics site.
