10 - 9 = 1 + 19 - 3 - 12 = 5
The elevator ended up on the 5th floor.

To find the final floor of the elevator after going through these movements, we can start by determining the initial position on the 10th floor.
Since the elevator goes down 9 floors, we subtract 9 from the initial position of the 10th floor. 10 - 9 = 1. The elevator is now on the 1st floor.
Next, the elevator goes up 19 floors. We add 19 to the current position on the 1st floor. 1 + 19 = 20. The elevator is now on the 20th floor.
After that, the elevator goes down 3 floors. We subtract 3 from the current position on the 20th floor. 20 - 3 = 17. The elevator is now on the 17th floor.
Lastly, the elevator goes down 12 floors. Subtracting 12 from the current position on the 17th floor gives us: 17 - 12 = 5. The elevator is now on the 5th floor.
Therefore, after going down 9 floors, up 19 floors, down 3 floors, and finally down 12 floors, the elevator ends up on the 5th floor.
