yeah your right.....
its subtract two not add two..
27 + 2 = 29
we have already taken 3 off of the total
30 - 3 = 27
27 - 2 = 25
25 = the total bill
Very tricky one but very obvious at the same time
That dollar in a sense is given to the waitress.edit on 29-8-2011 by ShadowZion because: (no reason given)

Well, forgetting infinity for a moment, I recently realised too that 0 is not really something which could be considered a number since it means that there is nothing.
Therefore, to count to "10", you have
1, 2, 3, 4, 5, 6, 7, 8, 9, 10 (one "nine" plus "nothing" units)
but the problem is, in base 10, by saying 9+nothing (10) , we really mean 9 + 1. But Zero means a lack of something. So zero (as a symbol) changes its meaning as soon as you get away from 0.
