What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: XI, X > I, so XI = X + I = 10 + 1 = 11
 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 2 or 3 times, they get added. For example: II = I + I = 1 + 1 = 2
 The same letter cannot be used more than three times in succession.

MMMCXX Roman Numerals Examples

Example 2: Find the Difference Between MMMCXX and MMCLV.
Solution:
Roman Numeral MMMCXX is equal to 3120 and MMCLV is 2155.
Now, MMMCXX  MMCLV = 3120  2155 = 965
Since, 965 = CMLXV
Therefore, MMMCXX  MMCLV = CMLXV 
Example 3: Find the Sum of CXCI and MMMCXX Roman Numerals.
Solution:
CXCI = 100 + 90 + 1 = 191 and MMMCXX = 3000 + 100 + 20 = 3120
Now, CXCI + MMMCXX = 191 + 3120 = 3311
