1 - The natural numbers

This is an introductory lesson to the natural numbers unit.

Do you remember what a natural number is?

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...
