Question

-2,-1,0,1
Which pair of numbers has a sum of zero
1,1
-2,0
-2,1
-1,0

Answer 1

Numbers that add to zero are called additive inverses or opposites.

Answer 2

I was think that the answer is -1,1

Answer 3

0 is its own additive inverse, since 0 + 0 = 0
For all other opposites (or additive inverses), pick any number and the same number with the opposite sign, and they are additive inverses.

Answer 4

Additive inverses:
2, -2
4, -4
-5, 5
-8.9, 8.9
-100, 100

Answer 5

So -1,1
