The numbers are 3, 7, and 11.
Answer:
0
Step-by-step explanation:
Opposite numbers lie on opposite sides of 0 but are the same distance from 0. For example, the opposite of 3 is -3, and both those numbers are on opposite sides of 0, both 3 units from it.
The opposite of -4 is 4. Those are on opposite sides of 0 and both are 4 units from it.
Zero?
The opposite of 0 is 0 itself! The symbol -0 can be confusing if you read that as "negative zero" and expect it to be on the negative side of the number line. It's better to read that as "the opposite of zero" or, if you want to sound overly smart (but even more correct!), say "the additive inverse of 0".
This all leads up to the idea of absolute value of a number: its distance from 0.
|3| = 3
|-4| = 4
|0| = 0
