Basic Rules to Interpret Roman Numerals
 When a bigger letter precedes a smaller letter, the letters are added. For example: MX, M > X, so MX = M + X = 1000 + 10 = 1010.

 When a letter is repeated multiple times, they get added. For example: CCC = C + C + C = 100 + 100 + 100 = 300
 The same letter cannot be used more than three times in succession.
