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?

Answer 1

Solution:

As the Options are not given

6 + (-8)

It means Ahmed is on the Sixth floor, above the ground floor and then goes 8 floor Downwards which is 2 level below the ground floor.

The Answer in form of numbers is = -2

Because when we add a positive integer and a negative integer , we just subtract smaller integer from larger integer , and keep that sign before the result which the larger number bears.

6 + (-8)=

8 is larger integer which bears negative sign.

One integer is positive and another one is negative,

8 -6= 2

So, 6 + (-8) = -2 →→   2 level below the ground level

I have drawn number line for you.

Answer 2

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

I hope this helps.
