## genny7 one year ago What is the sum of a real number and its additive inverse?

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? :)
