I'm not sure that people necessarily know what questions they need to ask, or even that they need to ask.

A math Q&A seems like a good idea, but it would be a better idea if there were some "the math you need for LW" posts first.

There was a very nice piece here (possibly a quote) on how to think about math problems-- no more that a few paragraphs long. It was about how to break things down and the sorts of persistence needed. Anyone remember it?
