 Number Line:

Number line is an imaginary line which is used to represent whole numbers on it keeping equal

gaps between each numbers.

Representation of whole numbers on the line helps us to compare between two whole numbers i.e.
to decide which of the two given whole numbers is greater or smaller.

Example:

0 10 20 80

As 20 is right of 10, so 20 is greater than 10 i.e. 20 > 10.

As 10 is left of 80, so 10 is less than 80 i.e. 10 < 80.
