why when you learn your times tables (when your a kid at school) do they only bother to go up to x 12 on any given times table and then only up to your 12 times table?

That is all you ever need now, used to be up to 16
Everything above that is multiples thereof
Harks back to the old days of imperial measurements and so was reduced to 12 when metric was introduced
My school refused to teach us anything about imperial measurements
Then we pointed out some items which were (and are still are) measured by imperial
As a result they had to send a letter out to all parents in that class to ask if they would consent to the class being taught imperial, the result was an oustanding 95%
However this meant the pupils that responded no had to be excluded!
A later class showed us how to use a slide-rule, another item that had been withdrawn from schools in 1983

They should only teach times tables up to 10 in my opinion, then teach how to use what they've already learnt to do larger sums. For example, for 16 x 17, they should be taught to realise that they need to calculate (10 x 17) + (6 x 17), and so on and so forth.
yes I was only ever taught up to 12x tables and that was back in the 60's .... Not sure where someone get this was changed because of decimalisation
Working offshore we rely heavily on imperial. Most people struggle with cm and mm!
I was taught upto 12 times and both my kids have.
as stated- only went to x12/12x12
not done those since I was 7 lol
