Answer: He moved 6 floors up, then moved 8 floors down. So he is now 2 floors below ground level.

I hope this helps.

Answer:

Explanation:

The question is incomplete. Here is the complete question

Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement. 6 + (–8) Which statement could describe Ahmed’s movement?

Given the expression

6+(-8)

Let's denote upward movement in the elevator as positive and downward movement as negative.

+6 means that Ahmed rides 6 floors above in the elevator (since +be means upward movement in the elevator)

-8 means that from that 6th floor, he then moves 8 floors downwards in the elevator. In other to determine the floor Ahmed is, we can evaluate the given expression:

= 6+(-8)

Note that -×+ = -, hence the expression becomes;

= 6-8

= -8+6

= -2

This means that Ahmed is 2 floor below or down the elevator.
