Being from north of Bury, he had to stop at 12 because he'd run out of fingers.

North Lancashire and East Cambridgeshire are my main hiring spots for fingering and fisting roles. Lincolnshire at a push if demand outstrips supply.

And at that point you reached your limit, explains a lot!

I thought it was £sd when you were a lad

It was for me.

Don't they just stick them in the tuck shop after learning their 8 times table anymore? Crisps and chocolate bars at 8p a time means we learnt adding up and taking away and money management skills as well.

Made me the man I am.

Ability to do long division is useful for factorising equations - which in turn can help with differentiation or integration.

Short division is piss easy if you've learned your times tables off by heart from 1 to 12. No need for any subtractions or anything (at least, not to write down).

8729/7
7 goes into 8 once, so write down 1 
put the remainder 1 next to the 7 ->17
7 goes into 17 twice, so write down 2
put the remainder 3 next to the 2 -> 32
7 goes into 32 four times, so write down 4
put the remainder 4 next to the 9 -> 49
7 goes into 49 seven times, so write down 7.
No remainder, so we're done.

That’s the way i tried to do it before I was told I was wrong to be fair given it’s his school work I’m going with what he’s been told as being right for him and his teacher

let me guess he moved onto working in something that rhymes with Tuckshop?

Via the Suckshop (motto: one swallow does not a bummer make)

[vetran]

He had to deal with sums as big as 12p, even 15p, with his under the counter special menu.

Amateurs. Every self-respecting mathematician will subtract the log of the denominator from the log of the numerator, and raise ten to the power of the result

No self-respecting mathematician deals with anything as vulgar as actual numbers.

daughter in year 4.
Doing place value tables, which is OK.
Then we did partitioning, which relies on knowledge of place value tables so pointless.

She hates division but is OK at nmost stuff. As was I when I was young.
I keep telling her that once she's learned the method she can use a calculator and never do it again. As I did some years ago.

That's the key to it - there will always be a time when you just need to know enough to sense check a number (and not necessarily accurately) without getting a calculator out. If you have a rough idea of the basic maths then many things in life will be a lot easier.

My son is in Year 6 and I think in old money it would be called long division but I have just been shown "the bus stop method" and although it works, it just seems crazy!

This. Long division I learned in a similar way.

But back then teachers were like "ooh, you'll not always have a calculator with you."

Your move Mrs Simpson....
