Basic Rules to Interpret Roman Numerals
 When a bigger letter precedes a smaller letter, the letters are added. For example: CI, C > I, so CI = C + I = 100 + 1 = 101.
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CM, C < M, so CM = M  C = 1000  100 = 900.
 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.
