OOOPS!!!! Never was good at mental arithmetic and it was a long long time ago and I am old enough to remember dividing £ s d, not that I could ever do it. I think all the fuss that we 3 children used to kick up in the back of the car was about having the money immediately and not waiting until our beleaguered mum and dad could find the right change for each one of us. > They each got £1-13-4. Quite straightforward.
