One student asked me how to solve a problem and the only way of solving it that came to me seems hopeless to find an answers. It occurred to me that I may using a wrong approach to it. How could I ask for help in this case in MO? Could I just post the tittle "What tools should I use for this problem?" and then to describe the problem and my attempt in the body of the question?

ps1: I read in How do I ask a good question? that "*If your question is about the site itself, ask on our meta-discussion site*". So I did it.

ps2: I didn't write about the problem here because I intend to post in MO for a complete discussion. But if is good, I can write the problem here.

ps3: Once I know how to ask it in MO, I will put a link to the question here. **Edit:** I posted the question: What tools should I use for this problem?
