Rules to Write Roman Numerals
There are certain rules to be followed while presenting a number in Roman numerals which are as follows:
The value of the symbol is added to itself as many times as it is repeated. For example II = 2, XX = 20, XXX = 30.
Symbols such as V, L, and D are never repeated and are never subtracted.
When a symbol of a smaller value appears after a symbol of greater value, its value will be added for example- VI = V + I =5 + 1 = 6.
When a symbol of smaller value appears before a symbol of greater value symbol, its value will be subtracted for example IX = X - I = 10 -1 = 9
The symbol I can be subtracted from V and X only and symbol X can be subtracted from symbols L, M, and C only.
Also, we can clearly understand that there is no requirement of writing zeros to represent 50 or 100; we can just write L and C. Thus, these letters are considered to be very easy and indicate the entire number system.
