In grade school did you learn the multiplication table through 10 or through 12?

I once had a student from Senegal who said his school made them learn through 15... I was a little jealous.

(I only learned through 10, but have picked up most of 11 and 12 slowly over time...I resent that I'll never know those as easily as the single digits. I wish I'd been forced to learn all the way to 20 tbh.)

@futurebird not as useful as tools tho. what galls me is that schools scare kids with this huge chart of 144 things they gotta either memorize or look up.

there's lots of patterns in multiplication and so there are only about 30 really hard ones you gotta memorize.

y even put 1s and 10s on there? pattern to 5s, 2s 4s and 8s is just lots of doubling. 9s thers a pattern...

11s and 12s just there to scare kids.

school sucks.

@barrygoldman1 @futurebird YES THIS all of this

(and of course in addition to my other reply: we never drilled 1 through 3 either, because by the time we had gone from 9 through 4 everything in the 2 and 3 sequences was already repeated far more times than the higher numbers anyway, and 1 was completely pointless, and 5 was just half and move decimal point, so 1,2,3,5 were only included as mnemonics and i only ever rote-memorized 9, 8, 7, 6, 4 for 5*9=45 equations* for the entire inventory of multiplication math facts that i didn't just pick up from frequent actual use)

*(obviously less than this if you count 9x4 and 4x9 as the same, but my math-math isn't good enough for me to figure out exactly how many uniques there are without brute-forcing it)
