What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: LX, L > X, so LX = L + X = 50 + 10 = 60
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XL, X < L, so XL = L  X = 50  10 = 40
 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.

MDCCLXVI Roman Numerals Examples

Example 1: Evaluate the following expression: MDCCLXVI  LXXX + XI.
Solution:
MDCCLXVI = 1766, LXXX = 80, and XI = 11
⇒ MDCCLXVI  LXXX + XI = 1766  80 + 11 = 1697
⇒ The difference is 1697, which can be written as MDCXCVII. 
Example 2: Find the Sum of CDLIX and MDCCLXVI Roman Numerals.
Solution:
CDLIX = 400 + 50 + 9 = 459 and MDCCLXVI = 1000 + 700 + 60 + 6 = 1766
Now, CDLIX + MDCCLXVI = 459 + 1766 = 2225
Since, MMCCXXV = 2000 + 200 + 20 + 5 = 2225
Therefore, the sum of CDLIX and MDCCLXVI roman numerals is MMCCXXV
