I got my BS in engineering (electrical), managed to scrape my way through all the hard math classes, but never really had a firm grasp on any of it. A bit later on in the real world, doing some signal processing work, some of it started to snap together. But then I read the Structure and Interpretation of Computer Programs. Which I found to be more math heavy than any other prob books I'd read previously. But the way everything was describe, and laid out in the context of programming, all my past math just came streaming back, and suddenly made sense. It was like that "a-ha" moment, times 1000. I don't know what the point of my ramblings are. I guess math finally made sense after learning programming first, much like yegge proposes in his post. But I had the basics down first, and I was at least familiar with the concepts.
