I wouldn't say I'm great at math, I scraped an A-Level in it over twenty years ago, didn't use it much for years, but then I got interested in graphics again and there are some severe gaps in my knowledge. I remember at the time, I just did not understand matrices, I now use them a hell of a lot and I still suck at them. Linear algebra is another one. Most other stuff day to day stuff I can reasonably understand, or at least sit down with pen and paper and work out what I need to do but the above 2 frequently get my head stuck in knots, I often think about maybe doing a course on these 2
