… Nearly all of the math I actually use I learned in the 6th grade or earlier, overwhelmingly elementary school arithmetic—mostly the "bad" kind I got from memorization-based practice that mathematicians seem to hate even though it's a contender for the best bang-for-buck of almost my entire educational career, plus a lot of fractions-related stuff (so, so very many people are terrible at this, can't even do basic things, IME it's where an awful lot of people permanently fall off the math-train, way back in like 3rd grade), basic arithmetic, and pre-algebra-tier simple variable substitution. Every now and then I get a bug up my ass to try to expand my math abilities, but 1) I'm so goddamn rusty at this point because I never use any of it that I have to start back at brushing up on high school stuff, which is discouraging, and 2) I'm not even really sure what I'm going to do with it (long experience suggests: nothing) so the motivation fades fast.

I’m with you except for 2. Knowing math is great.

I do agree high level math isn't as useful for dev work. I have a masters in math and started working as a data analyst. I moved to programming years ago and I basically never really need to use the math stuff I know anymore. Weirdly my math background is actually more useful as a 'soft' skill in my current work. I am the go to person for talking to the data analysts in my company, and having a statistics background is pretty helpful for interfacing with managers or people outside the dev department. Every once in a while I remember an algorithm for doing something I can include in our app and feel like a God, lol.

You're probably using math without knowing it. Debugging through a piece of code is the same as finding a hole in a proof. "This method HAS to return the right value because C. C is always true because B. B is true because A. Ohh... but A isn't true if the record passed in is for a legacy user with no org manager. The method needs to be changed to work for inputs that don't satisfy the current assumptions." It's not the math facts you learn so much as getting lots of practice with that kind of reasoning.
