For each positive integer, there is a negative integer, and these integers are called opposites. For example, -3 is the opposite of 3. 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.

Note that the opposite of a positive integer is a negative integer, and the opposite of a negative integer is a positive integer. The absolute value of an integer is its distance from zero on a number line. For example, the absolute value of -8 is +8, because -8 is 8 units from zero on the number line.
It is neither positive nor negative. The sign of an integer is either positive (+) or negative (-), except zero, which has no sign. Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line.
Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., –(–3) = 3, and that 0 is its own opposite.
the opposite of a positive number is always negative and the opposite of a negative number is always positive. The absolute value of a number is the number of units that the number is from zero on the number line. Absolute value only measures distance.
