MCMXX Roman Numerals
MCMXX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. MCMXX = M + CM + XX = 1000 + 900 + 20 = 1920. The higher roman numerals precede the lower numerals resulting in the correct translation of MCMXX Roman Numerals. In this article, we will explain how to convert MCMXX Roman numerals in the correct number translation.
 MCMXX = M + (M  C) + X + X
 MCMXX = 1000 + (1000  100) + 10 + 10
 MCMXX = 1920
How to Write MCMXX Roman Numerals?
The numerical value of MCMXX 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.
 MCMXX = M + (M  C) + X + X = 1000 + (1000  100) + 10 + 10 = 1920
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MCMXX = M + CM + XX = 1000 + 900 + 20 = 1920
Therefore, the numerical value of MCMXX roman numerals is 1920.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: CX, C > X, so CX = C + X = 100 + 10 = 110
 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: II = I + I = 1 + 1 = 2
 The same letter cannot be used more than three times in succession.
Numbers Related to MCMXX Roman Numerals
Roman numerals were used in ancient Rome and utilized combinations of letters using the Latin alphabets I, V, X, L, C, D, and M. It may seem different than numbers, but they are similar. For example, MCMXX Roman numerals are equivalent to the number 1920. The roman numerals related to MCMXX are given below:
 MCMXX = 1000 + 900 + 20 = 1920
 MCMXXI = 1000 + 900 + 20 + 1 = 1921
 MCMXXII = 1000 + 900 + 20 + 2 = 1922
 MCMXXIII = 1000 + 900 + 20 + 3 = 1923
 MCMXXIV = 1000 + 900 + 20 + 4 = 1924
 MCMXXV = 1000 + 900 + 20 + 5 = 1925
 MCMXXVI = 1000 + 900 + 20 + 6 = 1926
 MCMXXVII = 1000 + 900 + 20 + 7 = 1927
 MCMXXVIII = 1000 + 900 + 20 + 8 = 1928
 MCMXXIX = 1000 + 900 + 20 + 9 = 1929
MCMXX Roman Numerals Examples

Example 2: Evaluate the following expression: MCMXX  LVII + XI.
Solution:
MCMXX = 1920, LVII = 57, and XI = 11
⇒ MCMXX  LVII + XI = 1920  57 + 11 = 1874
⇒ The difference is 1874, which can be written as MDCCCLXXIV. 
Example 3: Find the Difference Between MCMXX and CXLIX.
Solution:
Roman Numeral MCMXX is equal to 1920 and CXLIX is 149.
Now, MCMXX  CXLIX = 1920  149 = 1771
Since, 1771 = MDCCLXXI
Therefore, MCMXX  CXLIX = MDCCLXXI 
Example 4: Find the Sum of DCCXXX and MCMXX Roman Numerals.
Solution:
DCCXXX = 700 + 30 = 730 and MCMXX = 1000 + 900 + 20 = 1920
Now, DCCXXX + MCMXX = 730 + 1920 = 2650
Since, MMDCL = 2000 + 600 + 50 = 2650
Therefore, the sum of DCCXXX and MCMXX roman numerals is MMDCL
