The absolute value of an integer is its distance from 0 on the number line.

How to determine the Opposites of Integers?
To find the opposite of an integer, we just change its sign. If it is negative, change to positive. If it is positive change to negative.
Opposite integers are the pairs of integers that have the same absolute value, or the same distance from zero.
The sum of two opposites is always zero.
This video provides two examples of determining the opposite of a given integer.
Examples:
What is the opposite of 4?
What is the opposite of -9?
