What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: CL, C > L, so CL = C + L = 100 + 50 = 150
 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: CC = C + C = 100 + 100 = 200
 The same letter cannot be used more than three times in succession.

DCCXX Roman Numerals Examples

Example 1: Find the Sum of MDIV and DCCXX Roman Numerals.
Solution:
MDIV = 1000 + 500 + 4 = 1504 and DCCXX = 700 + 20 = 720
Now, MDIV + DCCXX = 1504 + 720 = 2224
Since, MMCCXXIV = 2000 + 200 + 20 + 4 = 2224
Therefore, the sum of MDIV and DCCXX roman numerals is MMCCXXIV 
Example 3: Find the Product of Roman Numerals DCCXX and IV.
Solution:
DCCXX = 700 + 20 = 720 and IV = 4
Now, DCCXX × IV = 720 × 4 = 2880
Since, MMDCCCLXXX = 2000 + 800 + 80 = 2880
Therefore, DCCXX × IV = MMDCCCLXXX 
Example 4: Find the Difference Between DCCXX and CXXX.
Solution:
Roman Numeral DCCXX is equal to 720 and CXXX is 130.
Now, DCCXX  CXXX = 720  130 = 590
Since, 590 = DXC
Therefore, DCCXX  CXXX = DXC
