Basic Rules to Interpret Roman Numerals
 When a bigger letter precedes a smaller letter, the letters are added. For example: LX, L > X, so LX = L + X = 50 + 10 = 60.
 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: MMM = M + M + M = 1000 + 1000 + 1000 = 3000
 The same letter cannot be used more than three times in succession.
