And you should have been there when we were trying to learn long multiplication or division based on L S D....Class take 3 pounds 6 shillings and tuppence and multiply by 8!

OK ... so 8 x tuppence is 16 pennies which of course is 1/- and 4 pennies so you carry the shilling over to the shillings column and hold the four pennies.

Then take 6 shillings x 8 == 48 shillings plus the one you carried which is 49 shillings and as there are 20 shillings in a pound, move 40 shillings into the pounds column, for two pounds and hold the remaining 9 shillings.

Then three pounds x 8 = 24 pounds plus the two you carried over

EQUALS......

26 pounds nine shillings and fourpence -- and NONE of it divisible by 10. You guys don't even begin to understand math anxiety!!!
