Question

What is the sum of a real number and its additive inverse?

Answer 1

The additive inverse of a number \(\large\rm x\) is going to be \(\large\rm -x\).
So the additive inverse of \(\large\rm 2\) is \(\large\rm -2\).
When we add \(\large\rm 2\) and \(\large\rm -2\) together, they give us the additive identity element.
What number is that? :)
