Answer:

y = x - 5 + 5

Step-by-step explanation:

Let x be the the original position and y be the new position.

After rid down, 5 floors, the expression would be y = x - 5.

After rid back up 5 floors, the expression changed to y = x - 5 + 5.

Hence, the required expression is y = x - 5 + 5 = x.

The expression is ' 0 ', as in 'zero'. If it were anything else, then that wouldn't help you go back to where you started and get what you forgot.
