Finding Opposites of Integers
To find the opposite of an integer, identify the number that lies at the same distance from zero on the number line but on the other side:
- The opposite of is , because is the same distance from as but on the left side.
- The opposite of is , because is the same distance from as but on the right side.
- : The expression means "the opposite of ." Since lies the same distance from as but on the opposite side, the result is .
In particular, taking the opposite of a negative number always produces a positive number: when is positive.
