In this article, we will explain how to convert MDXX Roman numerals in the correct number translation.
 MDXX = M + D + XX
 MDXX = 1000 + 500 + 20
 MDXX = 1520
How to Write MDXX Roman Numerals?
The numerical value of MDXX 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.
 MDXX = M + D + X + X = 1000 + 500 + 10 + 10 = 1520
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MDXX = M + D + XX = 1000 + 500 + 20 = 1520

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: 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.

MDXX Roman Numerals Examples

Example 1: Find the Difference Between MDXX and CC.
Solution:
Roman Numeral MDXX is equal to 1520 and CC is 200.
Now, MDXX  CC = 1520  200 = 1320
Since, 1320 = MCCCXX
Therefore, MDXX  CC = MCCCXX 
Example 2: Find the Sum of DLXXXIII and MDXX Roman Numerals.
Solution:
DLXXXIII = 500 + 80 + 3 = 583 and MDXX = 1000 + 500 + 20 = 1520
Now, DLXXXIII + MDXX = 583 + 1520 = 2103
Since, MMCIII = 2000 + 100 + 3 = 2103
Therefore, the sum of DLXXXIII and MDXX roman numerals is MMCIII 
Example 3: Evaluate the following expression: MDXX  LIX + XVIII.
Solution:
MDXX = 1520, LIX = 59, and XVIII = 18
⇒ MDXX  LIX + XVIII = 1520  59 + 18 = 1479
⇒ The difference is 1479, which can be written as MCDLXXIX.
