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.
