They are the numbers that are placed on a number line that are exact same distance away from 0
Negative and Positive numbers. Ex. -4 & 4 are the same distance from zero which is 4.
The numbers 1,2,3,... etc are called natural numbers or counting numbers. Integers are the natural numbers plus zero plus the negative ( or opposite ) natural numbers. Why do we need negative natural numbers ? For one thing x + 1 = 0 is an equation whose solution is x = -1. We could not solve this equation if we did not have negative integers. So over history these negative numbers came about as a way to solve certain math problems. The numbers 1,2,3,... etc are called natural numbers or counting numbers.

The opposite of negative is positive. In mathematics, the term "negative" refers to numbers less than zero, while "positive" refers to numbers greater than zero. These terms are used to describe the direction or sign of a number on the number line.
