Roman numerals are a system of numerical notations used by the Romans. They are an additive (and subtractive) system in which letters are used to denote certain "base" numbers, and arbitrary numbers are then denoted using combinations of symbols.

We can't use same symbol more than 3 times in a row. When we place same symbols together, we can just add their values.
If we place one or more smaller symbols values after the large symbols value, we add the smaller number to the larger number.
If we place smaller symbols values before the large symbol value, we subtract the smaller number from the larger number.
Only I, X and C are used for addition and subtraction I can be added or subtracted from V and X only.
