Do people actually learn multiplication beyond single digits? I know up to 12x12 and do math a few hours a day for work.

- Klockan 10y agoI am fairly sure that almost everyone with a cs degree can calculate something like 56 * 13 with a pen, paper and some time. The thing is that you can teach almost anyone to memorize a table which is why you can teach them to multiply single digits. But once you try to teach them how to follow an algorithm a lot of people just wont get it, which is why multiplying things they haven't memorized gets almost impossible for some.
- irrational 10y agoWell, he has never been able to memorize the multiplication table. But if you try to get him to solve 10 x 13 he just can't do it. But he can solve 3 x 3 with a pencil, paper, and his fingers or some manipulatives.
