CMXXX Roman Numerals
CMXXX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. CMXXX = (M  C) + X + X + X = (1000  100) + 10 + 10 + 10 = 930. The higher roman numerals precede the lower numerals resulting in the correct translation of CMXXX Roman Numerals. In this article, we will explain how to convert CMXXX Roman numerals in the correct number translation.
 CMXXX = CM + XXX
 CMXXX = 900 + 30
 CMXXX = 930
How to Write CMXXX Roman Numerals?
The numerical value of CMXXX Roman Numerals can be obtained by using any of the two methods given below:
Method 1: In this method, we break the roman numerals into single letters, write the numerical value of each letter and add/subtract them.
 CMXXX = (M  C) + X + X + X = (1000  100) + 10 + 10 + 10 = 930
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 CMXXX = CM + XXX = 900 + 30 = 930
Therefore, the numerical value of CMXXX roman numerals is 930.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MD, M > D, so MD = M + D = 1000 + 500 = 1500
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CD, C < D, so CD = D  C = 500  100 = 400
 When a letter is repeated 2 or 3 times, they get added. For example: MM = M + M = 1000 + 1000 = 2000
 The same letter cannot be used more than three times in succession.

CMXXX Roman Numerals Examples

Example 1: Find the Difference Between CMXXX and LXXXIX.
Solution:
Roman Numeral CMXXX is equal to 930 and LXXXIX is 89.
Now, CMXXX  LXXXIX = 930  89 = 841
Since, 841 = DCCCXLI
Therefore, CMXXX  LXXXIX = DCCCXLI 
Example 3: Find the Product of Roman Numerals CMXXX and II.
Solution:
CMXXX = 900 + 30 = 930 and II = 2
Now, CMXXX × II = 930 × 2 = 1860
Since, MDCCCLX = 1000 + 800 + 60 = 1860
Therefore, CMXXX × II = MDCCCLX 
Example 4: Find the Sum of DLXXI and CMXXX Roman Numerals.
Solution:
DLXXI = 500 + 70 + 1 = 571 and CMXXX = 900 + 30 = 930
Now, DLXXI + CMXXX = 571 + 930 = 1501
Since, MDI = 1000 + 500 + 1 = 1501
Therefore, the sum of DLXXI and CMXXX roman numerals is MDI
