What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MX, M > X, so MX = M + X = 1000 + 10 = 1010
 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: MMM = M + M + M = 1000 + 1000 + 1000 = 3000
 The same letter cannot be used more than three times in succession.

CXXX Roman Numerals Examples

Example 2: Find the Difference Between CXXX and XXVI.
Solution:
Roman Numeral CXXX is equal to 130 and XXVI is 26.
Now, CXXX  XXVI = 130  26 = 104
Since, 104 = CIV
Therefore, CXXX  XXVI = CIV 
Example 3: Find the Product of Roman Numerals CXXX and V.
Solution:
CXXX = 100 + 30 = 130 and V = 5
Now, CXXX × V = 130 × 5 = 650
Since, DCL = 600 + 50 = 650
Therefore, CXXX × V = DCL 
Example 4: Find the Sum of MMCCXLII and CXXX Roman Numerals.
Solution:
MMCCXLII = 2000 + 200 + 40 + 2 = 2242 and CXXX = 100 + 30 = 130
Now, MMCCXLII + CXXX = 2242 + 130 = 2372
Since, MMCCCLXXII = 2000 + 300 + 70 + 2 = 2372
Therefore, the sum of MMCCXLII and CXXX roman numerals is MMCCCLXXII
