Hmmm.  I wonder how it works.  It got 4 out of 5 right.  

[greenking]

It would have got 5 out of 5 if your maths was good Simon  

I wouldnt leave till i worked it out  :brick:

Come on then GK, spill the beans.

I'm useless at these mathematical puzzles

[Simon]

I can't see how it can be mathmatical - it's not as though it's always the same answer - how does it know what number you're going to pick to start with?

[greenking]

OK Heres how it done  

The only possible answers are  9, 18, 27, 36, 45, 54, 63, 72, and 81.   These symbols are always the constant on any given go  

Is that mathmatical enough for you Simon  

 

[Simon]

OK, I see how it works, so in that case, my maths must have been shoddy to get one wrong!
