An elevator on the tenth floor goes down nine floors. Then it goes up 19 floors, down 3, and finally down 12. What floor does it end up on?
10 - 9 = 1
1 + 19 = 20
20 - 3 = 17
17 - 12 = 5
The floor they will end up on should be number 5.
The floor for people that don't know what floor they want to go on
10 - 9 + 19 - 3 - 12 = ?
floor 5
