Positive and Negative Integers

This blog now begins a series reviewing the basic concepts of algebra.

First we start with the integers, which are a set of whole numbers.

Negative integers are those less than 0
Positive integers are those greater than 0

i.e.
...-3,-2,-1,0,1,2,3...

The sign < means less than
The sign > means greater than

Thus
-3 < 1
3 > 2
3 > -2

and so on.
