I am doing abstract math most of the time so I occasionally forget some products, have to recompute those from neighbouring ones. You just forget stuff when you rarely use it, especially if it's memorization related.

7x8 was the hardest one to learn when I was 8, and it's still the hardest one to remember 20 years later. That fraction problem took me less time

Took me a minute to remember how you're supposed to multiply fractions. Haven't had to do any of that since, I think like 5th grade. Turns out you can live most of your life on decimals.
