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.

Yes this represents additive inverse,

 Since you are subtracting the same number 4 to get to zero.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
