Partial Credit?

by Chikashi

Someone popped in the other day for a chat, only to reveal that he thought that I will be riding a motorcycle to Edinburgh.  He added, ‘You’ll have a sore bum.’

I seem to recall that we got partial credit in maths for multiplying instead of dividing two bits even if we applied the correct operator to the wrong bits.  Or, did we?  I don’t remember any more.
