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
