 When a letter is repeated 2 or 3 times, they get added. For example: III = I + I + I = 1 + 1 + 1 = 3
 The same letter cannot be used more than three times in succession.

MMCXXX Roman Numerals Examples

Example 1: Find the Difference Between MMCXXX and DCCCVII.
Solution:
Roman Numeral MMCXXX is equal to 2130 and DCCCVII is 807.
Now, MMCXXX  DCCCVII = 2130  807 = 1323
Since, 1323 = MCCCXXIII
Therefore, MMCXXX  DCCCVII = MCCCXXIII 
Example 2: Evaluate the following expression: MMCXXX  LIV + VIII.
Solution:
MMCXXX = 2130, LIV = 54, and VIII = 8
⇒ MMCXXX  LIV + VIII = 2130  54 + 8 = 2084
⇒ The difference is 2084, which can be written as MMLXXXIV. 
Example 3: Find the Sum of MDCLXI and MMCXXX Roman Numerals.
Solution:
MDCLXI = 1000 + 600 + 60 + 1 = 1661 and MMCXXX = 2000 + 100 + 30 = 2130
Now, MDCLXI + MMCXXX = 1661 + 2130 = 3791
Since, MMMDCCXCI = 3000 + 700 + 90 + 1 = 3791
Therefore, the sum of MDCLXI and MMCXXX roman numerals is MMMDCCXCI
