When I need to do something math like I usually find some code that does something similar, figure out what it's up to and adapt it to my needs. Pretty pictures help a lot too.
Learned enough linear algebra this way to be productive, made a pie menu addon for blender that got adopted by other people and eventually became builtin -- mostly to bughunt and find missing chunks of the python API though.
Actually, now that I think about it, I pretty much learn everything this way.
