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: IX, I < X, so IX = X  I = 10  1 = 9.
 When a letter is repeated multiple times, they get added. For example: II = I + I = 1 + 1 = 2
 The same letter cannot be used more than three times in succession.
