Whole numbers and Integers

Whole Numbers are simply the numbers 0, 1, 2, 3, 4, 5, ... (and so on)
==Counting Numbers==
Counting Numbers are Whole Numbers, but without the zero. Because you can't "count" zero.
So they are 1, 2, 3, 4, 5, ... (and so on).
==Natural Numbers==
"Natural Numbers" can mean either "Counting Numbers" {1, 2, 3, ...}, or "Whole Numbers" {0, 1, 2, 3, ...}, depending on the subject.
==Integers==
Integers are like whole numbers, but they also include negative numbers ... but still no fractions allowed!
So, integers can be negative {-1, -2,-3, -4, -5, ... }, positive {1, 2, 3, 4, 5, ... }, or zero {0}
We can put that all together like this:
Integers = { ..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ... }
Example, these are all integers:
-16, -3, 0, 1, 198
(But numbers like ½, 1.1 and 3.5 are not integers)
