The Basics of Integers.

(Old topic, I know.)

Integers are sets of numbers, their opposites, and zero.
Examples: 1, 2, 3, 4, 0, -1, -2, -3, -4

Remember: Zero is neutral, it is not positive or negative.

Positive numbers are numbers above zero.
Negative numbers are numbers below zero.

A zero pair is a set of integers that equal zero.
Example: 1, -1

Opposite integers have the same numeral but different signs (positive or negative)
They are also the same distance away from zero on a number line.
