Answer:
Additive inverse
Step-by-step explanation:
Every real number has an additive inverse, i.e., for every real number x, there exists a real number y such that
[tex]x+y=0[/tex]
Obviously, y is simply -x.
So, in this case, we can see that 3 and -3 are additive inverse, because they give 0 when summed.
