Natural numbers are naturally
Numbers you count on your hands and your feet
1, 2, 3, 4, 5, 6, and so on

Whole numbers are natural numbers plus zero
That's the only difference, oh, oh
0, 1, 2, 3, and so on

Integers are whole numbers plus negatives
They look a little bit like this
-2, -1, 0, 1, and so on

Last but not least, not to be outdone
Rational numbers are integers plus fractions
Like -3, 1/2, 5/8 and 14.2

All natural numbers are whole numbers
All whole numbers are integers
All integers are rational numbers
Now listen to that drummer!

What about 4? It's a natural number so it's also whole, integer, and rational
What about -2? Integer and rational
What about 1.5? It's just rational
What about 0? It's whole, integer, and rational

All natural numbers are whole numbers
All whole numbers are integers
All integers are rational numbers
Now listen to that drummer!
