CMXX Roman Numerals
CMXX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. CMXX = (M  C) + X + X = (1000  100) + 10 + 10 = 920. The higher roman numerals precede the lower numerals resulting in the correct translation of CMXX Roman Numerals. In this article, we will explain how to convert CMXX Roman numerals in the correct number translation.
 CMXX = (M  C) + X + X
 CMXX = (1000  100) + 10 + 10
 CMXX = 920
How to Write CMXX Roman Numerals?
The numerical value of CMXX 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.
 CMXX = (M  C) + X + X = (1000  100) + 10 + 10 = 920
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 CMXX = CM + XX = 900 + 20 = 920
Therefore, the numerical value of CMXX roman numerals is 920.

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: IX, I < X, so IX = X  I = 10  1 = 9
 When a letter is repeated 2 or 3 times, they get added. For example: XXX = X + X + X = 10 + 10 + 10 = 30
 The same letter cannot be used more than three times in succession.

 CMXXI = 900 + 20 + 1 = 921
 CMXXII = 900 + 20 + 2 = 922
 CMXXIII = 900 + 20 + 3 = 923
 CMXXIV = 900 + 20 + 4 = 924
 CMXXV = 900 + 20 + 5 = 925
 CMXXVI = 900 + 20 + 6 = 926
 CMXXVII = 900 + 20 + 7 = 927
 CMXXVIII = 900 + 20 + 8 = 928
 CMXXIX = 900 + 20 + 9 = 929
CMXX Roman Numerals Examples

Example 1: Find the Product of Roman Numerals CMXX and III.
Solution:
CMXX = 900 + 20 = 920 and III = 3
Now, CMXX × III = 920 × 3 = 2760
Since, MMDCCLX = 2000 + 700 + 60 = 2760
Therefore, CMXX × III = MMDCCLX 
Example 2: Find the Sum of MCDLXXIX and CMXX Roman Numerals.
Solution:
MCDLXXIX = 1000 + 400 + 70 + 9 = 1479 and CMXX = 900 + 20 = 920
Now, MCDLXXIX + CMXX = 1479 + 920 = 2399
Since, MMCCCXCIX = 2000 + 300 + 90 + 9 = 2399
Therefore, the sum of MCDLXXIX and CMXX roman numerals is MMCCCXCIX 
Example 3: Find the Difference Between CMXX and CXLII.
Solution:
Roman Numeral CMXX is equal to 920 and CXLII is 142.
Now, CMXX  CXLII = 920  142 = 778
Since, 778 = DCCLXXVIII
Therefore, CMXX  CXLII = DCCLXXVIII
