Observe that, out of any two whole numbers, the number on the right is the greater number. [3 are to the right of 2. So 3 is the greater number and 2 is smaller]

The number line can be used to represent larger numbers.


The whole number 503 is on the left of the whole number 530 on the number line

So, or



The whole number 307 is on the left of the whole number 370 on the number line

So, or



The whole number 56789 is on the left of the whole number 98765 on the number line

So, or



The whole number 9830415 is on the left of the whole number 10023001 on the number line

So,
