On the Math Exchange I've had nothing but positive experience. The thing to do is first to struggle a bit with the problem and formulate a good question. Asking good question is an incredibly valuable skill. The questions which get treated bad are usually either poorly written and/or the person asking it clearly didn't even spend the bare minimum trying to solve it.
Here are some tips to get your questions answered and upvoted:
1) Spend some time on the problem
2) Describe what you've tried and why according to you that doesn't work or you don't understand it
3) Write in clear language and don't make obvious grammar mistakes
