The higher roman numerals precede the lower numerals resulting in the correct translation of CXX Roman Numerals. In this article, we will explain how to convert CXX Roman numerals in the correct number translation.
 CXX = C + XX
 CXX = 100 + 20
 CXX = 120
How to Write CXX Roman Numerals?
The numerical value of CXX 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.
 CXX = C + X + X = 100 + 10 + 10 = 120
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 CXX = C + XX = 100 + 20 = 120

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: III = I + I + I = 1 + 1 + 1 = 3
 The same letter cannot be used more than three times in succession.

CXX Roman Numerals Examples

Example 1: Find the Sum of MCMXX and CXX Roman Numerals.
Solution:
MCMXX = 1000 + 900 + 20 = 1920 and CXX = 100 + 20 = 120
Now, MCMXX + CXX = 1920 + 120 = 2040
Since, MMXL = 2000 + 40 = 2040
Therefore, the sum of MCMXX and CXX roman numerals is MMXL 
Example 2: Find the Product of Roman Numerals CXX and XXX.
Solution:
CXX = 100 + 20 = 120 and XXX = 30
Now, CXX × XXX = 120 × 30 = 3600
Since, MMMDC = 3000 + 600 = 3600
Therefore, CXX × XXX = MMMDC 
Example 3: Find the Difference Between CXX and LXXI.
Solution:
Roman Numeral CXX is equal to 120 and LXXI is 71.
Now, CXX  LXXI = 120  71 = 49
Since, 49 = XLIX
Therefore, CXX  LXXI = XLIX
