The Roman Numbers are use in clock faces, chapter numbering and class of students ( I - XII)

For example: DCCLXVI means: 500 + 100 + 100 + 50 + 10 + 5 + 1 = 766

List of some roman numerals and their numeric value as follows.

Disadvantages of Roman numerals

There is no symbol for zero, and there is no method to calculate fractions. These things hindered the ability to develop a universally understood, sophisticated math system, and made trading more difficult.
