Starting at the 10th floor, going down 9 floors puts the elevator on the 1st floor.
Going up 19 floors from the 1st floor puts the elevator on the 20th floor.
Going down 3 floors from the 20th floor puts the elevator on the 17th floor.
Finally, going down 12 floors from the 17th floor puts the elevator on the 5th floor.
Therefore, the elevator ends up on the 5th floor.
Equation: 10 - 9 + 19 - 3 - 12 = 5
