Answer:
2 numbers
Step-by-step explanation:
● -3 and 3 are both 3 units apart from 0
We can find it with calculations.
You are moving in a real numbers line.
You can move either right or left.
You starting point is 0.
When you go 3 units to the right then you are adding 3.
● 3+0 = 3
When you go back 3 units starting from 0 then you are substracting 3.
● 0-3 = -3
