DCXXX Roman Numerals
DCXXX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. DCXXX = DC + XXX = 600 + 30 = 630. The higher roman numerals precede the lower numerals resulting in the correct translation of DCXXX Roman Numerals. In this article, we will explain how to convert DCXXX Roman numerals in the correct number translation.
 DCXXX = D + C + X + X + X
 DCXXX = 500 + 100 + 10 + 10 + 10
 DCXXX = 630
How to Write DCXXX Roman Numerals?
The numerical value of DCXXX 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.
 DCXXX = D + C + X + X + X = 500 + 100 + 10 + 10 + 10 = 630
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 DCXXX = DC + XXX = 600 + 30 = 630

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: CI, C > I, so CI = C + I = 100 + 1 = 101
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: IV, I < V, so IV = V  I = 5  1 = 4
 When a letter is repeated 2 or 3 times, they get added. For example: XX = X + X = 10 + 10 = 20
 The same letter cannot be used more than three times in succession.

DCXXX Roman Numerals Examples

Example 2: Find the Sum of MMDCCCXI and DCXXX Roman Numerals.
Solution:
MMDCCCXI = 2000 + 800 + 10 + 1 = 2811 and DCXXX = 600 + 30 = 630
Now, MMDCCCXI + DCXXX = 2811 + 630 = 3441
Since, MMMCDXLI = 3000 + 400 + 40 + 1 = 3441
Therefore, the sum of MMDCCCXI and DCXXX roman numerals is MMMCDXLI 
Example 3: Find the Difference Between DCXXX and CVI.
Solution:
Roman Numeral DCXXX is equal to 630 and CVI is 106.
Now, DCXXX  CVI = 630  106 = 524
Since, 524 = DXXIV
Therefore, DCXXX  CVI = DXXIV 
Example 4: Find the Product of Roman Numerals DCXXX and I.
Solution:
DCXXX = 600 + 30 = 630 and I = 1
Now, DCXXX × I = 630 × 1 = 630
Since, DCXXX = 600 + 30 = 630
Therefore, DCXXX × I = DCXXX
