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

What are the Basic Rules to Write Roman Numerals?
- When a bigger letter precedes a smaller letter, the letters are added. For example: DX, D > X, so DX = D + X = 500 + 10 = 510
- 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: XX = X + X = 10 + 10 = 20
- The same letter cannot be used more than three times in succession.

XX Roman Numerals Examples
Example 1: Find the Product of Roman Numerals XX and CXXXIV.
XX = 20 and CXXXIV = 100 + 30 + 4 = 134
Now, XX × CXXXIV = 20 × 134 = 2680
Since, MMDCLXXX = 2000 + 600 + 80 = 2680
Therefore, XX × CXXXIV = MMDCLXXX
Example 2: Find the Sum of MMMCCCV and XX Roman Numerals.
MMMCCCV = 3000 + 300 + 5 = 3305 and XX = 20
Now, MMMCCCV + XX = 3305 + 20 = 3325
Since, MMMCCCXXV = 3000 + 300 + 20 + 5 = 3325
Therefore, the sum of MMMCCCV and XX roman numerals is MMMCCCXXV
Example 3: Find the Difference Between XX and XV.
Roman Numeral XX is equal to 20 and XV is 15.
Now, XX - XV = 20 - 15 = 5
Since, 5 = V
Therefore, XX - XV = V
