What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: DL, D > L, so DL = D + L = 500 + 50 = 550
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XC, X < C, so XC = C  X = 100  10 = 90
 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.

MDCCXX Roman Numerals Examples

Example 1: Evaluate the following expression: MDCCXX  LXXXIV + XIV.
Solution:
MDCCXX = 1720, LXXXIV = 84, and XIV = 14
⇒ MDCCXX  LXXXIV + XIV = 1720  84 + 14 = 1650
⇒ The difference is 1650, which can be written as MDCL. 
Example 3: Find the Difference Between MDCCXX and MLXXIV.
Solution:
Roman Numeral MDCCXX is equal to 1720 and MLXXIV is 1074.
Now, MDCCXX  MLXXIV = 1720  1074 = 646
Since, 646 = DCXLVI
Therefore, MDCCXX  MLXXIV = DCXLVI 
Example 4: Find the Sum of CDXCIX and MDCCXX Roman Numerals.
Solution:
CDXCIX = 400 + 90 + 9 = 499 and MDCCXX = 1000 + 700 + 20 = 1720
Now, CDXCIX + MDCCXX = 499 + 1720 = 2219
Since, MMCCXIX = 2000 + 200 + 10 + 9 = 2219
Therefore, the sum of CDXCIX and MDCCXX roman numerals is MMCCXIX
