80 sats \ 3 replies \ @Undisciplined 7 Feb \ on: Arithmetic skills do not transfer between applied and academic mathematics Education
Perhaps not directly relevant, but I recall one of my whacky math professors telling us that he was "a mathematician not an arithmetician", after making several arithmetic errors in a row.

When I had to calculate something in my head, I would often just estimate the result rather than find the exact answer, even if it was really simple. I just couldn’t be bothered to work it out fully if it didn’t matter.
Sometimes, I would even go out of my way to find a way to estimate the result instead of just doing the math normally in my head, lol
