MDCCXX Roman Numerals
MDCCXX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. MDCCXX = M + DCC + XX = 1000 + 700 + 20 = 1720. The higher roman numerals precede the lower numerals resulting in the correct translation of MDCCXX Roman Numerals. In this article, we will explain how to convert MDCCXX Roman numerals in the correct number translation.
 MDCCXX = M + D + C + C + X + X
 MDCCXX = 1000 + 500 + 100 + 100 + 10 + 10
 MDCCXX = 1720
How to Write MDCCXX Roman Numerals?
The numerical value of MDCCXX 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.
 MDCCXX = M + D + C + C + X + X = 1000 + 500 + 100 + 100 + 10 + 10 = 1720
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MDCCXX = M + DCC + XX = 1000 + 700 + 20 = 1720
Therefore, the numerical value of MDCCXX roman numerals is 1720.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: DL, D > L, so DL = D + L = 500 + 50 = 550
 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: II = I + I = 1 + 1 = 2
 The same letter cannot be used more than three times in succession.

For example, MDCCXX Roman numerals are equivalent to the number 1720. The roman numerals related to MDCCXX are given below:
 MDCCXX = 1000 + 700 + 20 = 1720
 MDCCXXI = 1000 + 700 + 20 + 1 = 1721
 MDCCXXII = 1000 + 700 + 20 + 2 = 1722
 MDCCXXIII = 1000 + 700 + 20 + 3 = 1723
 MDCCXXIV = 1000 + 700 + 20 + 4 = 1724
 MDCCXXV = 1000 + 700 + 20 + 5 = 1725
 MDCCXXVI = 1000 + 700 + 20 + 6 = 1726
 MDCCXXVII = 1000 + 700 + 20 + 7 = 1727
 MDCCXXVIII = 1000 + 700 + 20 + 8 = 1728
 MDCCXXIX = 1000 + 700 + 20 + 9 = 1729
MDCCXX Roman Numerals Examples

Example 1: Evaluate the following expression: MDCCXX  LXXXIV + XIV.
Solution:
MDCCXX = 1720, LXXXIV = 84, and XIV = 14
⇒ MDCCXX  LXXXIV + XIV = 1720  84 + 14 = 1650
⇒ The difference is 1650, which can be written as MDCL. 
Example 3: Find the Difference Between MDCCXX and MLXXIV.
Solution:
Roman Numeral MDCCXX is equal to 1720 and MLXXIV is 1074.
Now, MDCCXX  MLXXIV = 1720  1074 = 646
Since, 646 = DCXLVI
Therefore, MDCCXX  MLXXIV = DCXLVI 
Example 4: Find the Sum of CDXCIX and MDCCXX Roman Numerals.
Solution:
CDXCIX = 400 + 90 + 9 = 499 and MDCCXX = 1000 + 700 + 20 = 1720
Now, CDXCIX + MDCCXX = 499 + 1720 = 2219
Since, MMCCXIX = 2000 + 200 + 10 + 9 = 2219
Therefore, the sum of CDXCIX and MDCCXX roman numerals is MMCCXIX
