Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you typically count and they will certainly continue on right into infinity.

Whole numbers are all organic numbers consisting of 0 e.g. 0, 1, 2, 3, 4…

Integers include all totality numbers and their negative counterpart e.g. …-4, -3, -2, -1, 0,1, 2, 3, 4,…

All integers belengthy to the rational numbers. A rational number is a number

\$\$fracab,: b eq 0\$\$

Wbelow a and b are both integers.

Example

The number 4 is an integer and also a rational number. As it can be created without a decimal component it belongs to the integers. It is a rational number bereason it have the right to be created as:

\$\$frac41\$\$

Or

\$\$frac82\$\$

Or even

\$\$frac-8-2\$\$

Whereas

\$\$frac15=0.2\$\$

is a rational number yet not an integer.

A rational number composed in a decimal form can either be terminating as in:

\$\$frac15=0.2\$\$

Or repeating as in

\$\$frac56=0.83333...\$\$

All rational numbers belong to the genuine numbers.
