 DXX = D + X + X
 DXX = 500 + 10 + 10
 DXX = 520
How to Write DXX Roman Numerals?
The numerical value of DXX 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.
 DXX = D + X + X = 500 + 10 + 10 = 520
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 DXX = D + XX = 500 + 20 = 520

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MX, M > X, so MX = M + X = 1000 + 10 = 1010
 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: MMM = M + M + M = 1000 + 1000 + 1000 = 3000
 The same letter cannot be used more than three times in succession.

 DXXI = 500 + 20 + 1 = 521
 DXXII = 500 + 20 + 2 = 522
 DXXIII = 500 + 20 + 3 = 523
 DXXIV = 500 + 20 + 4 = 524
 DXXV = 500 + 20 + 5 = 525
 DXXVI = 500 + 20 + 6 = 526
 DXXVII = 500 + 20 + 7 = 527

DXX Roman Numerals Examples

Example 2: Find the Difference Between DXX and CDXXVIII.
Solution:
Roman Numeral DXX is equal to 520 and CDXXVIII is 428.
Now, DXX  CDXXVIII = 520  428 = 92
Since, 92 = XCII
Therefore, DXX  CDXXVIII = XCII 
Example 3: Find the Product of Roman Numerals DXX and VII.
Solution:
DXX = 500 + 20 = 520 and VII = 7
Now, DXX × VII = 520 × 7 = 3640
Since, MMMDCXL = 3000 + 600 + 40 = 3640
Therefore, DXX × VII = MMMDCXL 
Example 4: Find the Sum of MMDCCC and DXX Roman Numerals.
Solution:
MMDCCC = 2000 + 800 = 2800 and DXX = 500 + 20 = 520
Now, MMDCCC + DXX = 2800 + 520 = 3320
Since, MMMCCCXX = 3000 + 300 + 20 = 3320
Therefore, the sum of MMDCCC and DXX roman numerals is MMMCCCXX
