I was taught times tables only to the 9's ... the 10's and 11's were obvious and it wasn't until high school that I learned some other elementary schools taught the 12 table.
Well 10s kind of a gimme (add 0) and 11s kind of a gimme too (repeat the number with the exceptions of 10 and 11).
12 gives you a dozen, 12 hours, 60 minutes, and inches-feet unit of measure...
I think I just had to learn 0-10 in school but the others “get added to my quick recall” cache memory.
13 and up, not so much. But I can do 10 and 3...
It’s important to be right but speed will keep you from getting left behind.
See, back when WE went to school, there were only a few numbers, so it was a lot easier.
