DCCXX Roman Numerals
DCCXX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. DCCXX = D + C + C + X + X = 500 + 100 + 100 + 10 + 10 = 720. The higher roman numerals precede the lower numerals resulting in the correct translation of DCCXX Roman Numerals. In this article, we will explain how to convert DCCXX Roman numerals in the correct number translation.
 DCCXX = D + C + C + X + X
 DCCXX = 500 + 100 + 100 + 10 + 10
 DCCXX = 720
How to Write DCCXX Roman Numerals?
The numerical value of DCCXX 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.
 DCCXX = D + C + C + X + X = 500 + 100 + 100 + 10 + 10 = 720
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 DCCXX = DCC + XX = 700 + 20 = 720
Therefore, the numerical value of DCCXX roman numerals is 720.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: CL, C > L, so CL = C + L = 100 + 50 = 150
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CM, C < M, so CM = M  C = 1000  100 = 900
 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.

 DCCXXI = 700 + 20 + 1 = 721
 DCCXXII = 700 + 20 + 2 = 722
 DCCXXIII = 700 + 20 + 3 = 723
 DCCXXIV = 700 + 20 + 4 = 724
 DCCXXV = 700 + 20 + 5 = 725
 DCCXXVI = 700 + 20 + 6 = 726
 DCCXXVII = 700 + 20 + 7 = 727
 DCCXXVIII = 700 + 20 + 8 = 728
 DCCXXIX = 700 + 20 + 9 = 729
DCCXX Roman Numerals Examples

Example 1: Find the Sum of MDIV and DCCXX Roman Numerals.
Solution:
MDIV = 1000 + 500 + 4 = 1504 and DCCXX = 700 + 20 = 720
Now, MDIV + DCCXX = 1504 + 720 = 2224
Since, MMCCXXIV = 2000 + 200 + 20 + 4 = 2224
Therefore, the sum of MDIV and DCCXX roman numerals is MMCCXXIV 
Example 3: Find the Product of Roman Numerals DCCXX and IV.
Solution:
DCCXX = 700 + 20 = 720 and IV = 4
Now, DCCXX × IV = 720 × 4 = 2880
Since, MMDCCCLXXX = 2000 + 800 + 80 = 2880
Therefore, DCCXX × IV = MMDCCCLXXX 
Example 4: Find the Difference Between DCCXX and CXXX.
Solution:
Roman Numeral DCCXX is equal to 720 and CXXX is 130.
Now, DCCXX  CXXX = 720  130 = 590
Since, 590 = DXC
Therefore, DCCXX  CXXX = DXC
