* This was the answer provided, and I would have also said 22 as per stowie39. Unfortunately the answers came with no explanations. Maybe a slight trick question. Having given the question some thought the only explanation I could come up with is that with the +/- on the floor levels you end up with 22 but that does not take into account floor 0 - the 'ground floor' which would give you the 23.

Perhaps this puzzle is from USA, they call the ground floor floor 1, and so 1+7-3+16+2=23
