What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: ML, M > L, so ML = M + L = 1000 + 50 = 1050
 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: CCC = C + C + C = 100 + 100 + 100 = 300
 The same letter cannot be used more than three times in succession.

CDXXXVIII Roman Numerals Examples

Example 1: Find the Difference Between CDXXXVIII and CCLIII.
Solution:
Roman Numeral CDXXXVIII is equal to 438 and CCLIII is 253.
Now, CDXXXVIII  CCLIII = 438  253 = 185
Since, 185 = CLXXXV
Therefore, CDXXXVIII  CCLIII = CLXXXV 
Example 3: Find the Sum of DCCLXV and CDXXXVIII Roman Numerals.
Solution:
DCCLXV = 700 + 60 + 5 = 765 and CDXXXVIII = 400 + 30 + 8 = 438
Now, DCCLXV + CDXXXVIII = 765 + 438 = 1203
