Starting on the 10th floor, the elevator goes down 9 floors to the first floor, so it is now on the 1st floor.
Then it goes up 19 floors, bringing it to the 20th floor.
Next, it goes down 3 floors, bringing it to the 17th floor.
Finally, it goes down 12 floors, bringing it to the 5th floor.
Therefore, the elevator ends up on the 5th floor.
Equation: 10 - 9 + 19 -3 -12 = 5
