over two hundred solutions to this problem! I'm just sorry that
we can't mention you all. There seemed to be two different ways

from East Bergholt High School who wrote: If there was 1 egg in

also did the problem in this kind of way, but they used counters
to help them. Their Dad explained how they went about finding
the solution: Each had a piece of A4 paper and a pencil which
