Arianna runs up 4 flights of stairs and then runs down 4 flights of stairs. does this situation represent additive inverses?

The additive inverse of a number is simply the negation of the said number.

The given situation is an illustration additive inverse.

Given that:

Let:

When Arianna runs up, we have:

When Arianna runs down, we have:

---- the minus indicates a downward movement

So, we have:

The additive inverse of a number n is -n

E.g. The additive inverse of 7 is -7

By comparing x and y, we have:

and

Hence, the situation represents additive inverse.
