Question

Henry runs up 10 flights of stairs.

Then, he runs down 10 flights of stairs.
Does this situation represent additive
Inverses? Explain.

Answer 1

Yes, it does

Explanation:

When we add a number to its additive inverse, the resulting value is zero

The first case is running up 10 flights which we consider positive

then he runs down 10 flights of stairs; this we can consider as - 10

So adding this together, we have -10 + 10 to give zero

What this mean is that we have added a number to its additive inverse
