Positive and Negative Integers
"The Integers" is a part of real numbers.
The Integer is a whole number, i.e. if the number is greater than 0 (zero) called the Positve Integers and those numbers less than zero called the Negative Integers. Zero is neither positive nor negative.
For every Positive Integer, there's exist a Negative Integer whihc is equal distance from the origin (0).
Two integers that lie the same distance from the origin and located in opposite directions from the orign are called the opposites. For example, "positive 9" (+9) is the opposite of "negative 9." (-9).
