But maybe you did some mental arithmetic in your formative years? My friend was a math teacher and talked about the need to grasp the abstract concept of number. Which might be hard to grasp if you only ever pushed buttons from infancy?

I'm from the era before buttons.
But I got into computers in the 90s and my mental-math abilities atrophied.
I used to be able to remember everyone's birthday, address, and phone number, too.
My brain increasingly seems to be visual. I see really complex systems in my head, including ephemeral things, but I can't keep the numbers in line.
Must be all the software engineering rewiring my brain.
I was just thinking that I can spend hours philosophizing on the science of identifiers or the emotional impact of particular numerals, but can barely remember my multiplication tables.
Such an odd combination.
I'm unusually good at fractions because of all of the cooking, though, and at counting back change.
