Question

Moses got into an elevator. He went down 5 floors, up 6 floors and down 7 floors. He was then on the Second floor. On what floor did Moses get into the elevator​

Answer 1

Moses got into the elevator at the 8th floor.

Explanation:

Let's call the floor which Moses started at x. Going down decreases the floor number and going up increases the floor number. We then form the equation
`x-5+6-7=2` which is the same as
`x-8=0` which means
`x=8`. Moses got in at the 8th floor.
