I have exactly this, still have a lot of mental math. At school teachers just gave up at some point and gave me a calculator, I still have a lot of trouble with mental multiplication and converting between analog and digital time (doesn't help that in Dutch you say 15:30 like 'half four').
I'm also terrible at holding numbers in my head, if I do not keep paying conscious attention to it, they get reversed or substituted. I remember all my PIN's by the motion you used to input them instead of the number itself.
Programming made me discover how much I love math, but I still miss a lot of basics because I never 'got it' in elementary school, and thus ended up in the lowest levels of math in highschool, where it was extremely boring and tedious (because it was actually way to easy), I wish I could send a programming book/numberphile videos to my 12-year-old self, because I think I could have ended up using high-school time way more effectively, instead of just going through the motions.
