Hi Roelof,

I don't think you're far away - it could just be a typo/lack of care in 
writing it down. Have you tried putting some actual values into these 
rules? - that should help you understand what is wrong with what you've 
written down/get you closer to the correct solution.

For example: (x=2, y=4)  2^4 = 16 != 6 = 2 * 3

David.
