This is an introductory lesson to the natural numbers unit.

Do you remember what a natural number is?

We use natural numbers for counting (cardinal number) or ordering (ordinal number).

The** natural numbers** are ordered, so you can compare two** natural numbers**:

7** >** 4; 7 is greater than 4

3** <** 9; 3 is less than 9

The** natural numbers** are unlimited.

The digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 are used to write any natural number.

And in a number, the value of each digit depends on its position: units, tens, hundreds, thousand units...
