Answer 1

To solve this problem you must apply the proccedure shown below:

You have that the elevator travels up 14 floors and then down 6 floors, then it travels up 3 floors, up 7 floors, and down 12 floors. So, you only need to add and substract, as following:

$14-6+3+3-12=6$

Therefore, as you can see, the answer is: $6th$ floor.
