Basic Rules to Interpret Roman Numerals
 When a bigger letter precedes a smaller letter, the letters are added. For example: DC, D > C, so DC = D + C = 500 + 100 = 600.
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XL, X < L, so XL = L  X = 50  10 = 40.
 When a letter is repeated multiple times, they get added. For example: MM = M + M = 1000 + 1000 = 2000
 The same letter cannot be used more than three times in succession.
