**Opposites of integers and absolute value**

**Opposites of integers and absolute value**

For each positive integer, there is a negative

integer, and these integers are called opposites. For

example, -3 is the opposite of 3, -21 is the opposite

of 21, and 8 is the opposite of -8. If an integer is

greater than zero, we say that its sign is positive. If

an integer is less than zero, we say that its sign is

negative.
