That kinda describes my experience. I was never formally trained in computer science; I fell into it in my late twenties and taught myself. I never took math at the collegiate level, so I don't really understand the fundamentals. However, I am able to get by for about 95% of the things I've needed to do. But the last 5% is always the most interesting, and I hate it when I hit those walls.

well I hope there will always be that 5% left that you can't answer yet, and that you find interesting enough to learn more about. At the end of the day, that's probably the best way to learn more maths and get a deeper understanding of how computer programs work, at least that was the case for me who's, so far, been pretty bad at learning theory without having applied it first.
