Basic Rules for Writing Roman Numerals

1. The symbols are combined from largest to smallest.
Example: MXX = 1000 + 10 + 10 = 1020

2. A symbol cannot be repeated more than three times.
Example: III = 3 (correct), but IIII is wrong

3. Subtraction Rules: The smallest numeral before a larger number is subtracted.
Example: CM = 900 = 1000 – 100), XC = 90 = 100 – 10, IV = 4 = 5 – 1

4. Additional rules: A smaller numeral after a larger number is added.
Example: II = 1 + 1 = 2

5. V, L, and D are never repeated or subtracted.

Solved Examples on MXX Roman Numerals

Example 1: Convert MXX to numbers
Solution:
Break down a Roman numeral into its components:
M = 1000 and XX = 20

Now add them together: 1000 + 20 = 1020

 

Example 2: Convert 1020 to Roman numerals
Solution:
Step 1: Divide 1020 into thousands, hundreds, tens, and ones.
1020 = 1000 + 20 

Step 2: Convert each part to Roman numerals:
1000 = M
20 = XX
Step 3: Combine Them: M + XX = MXX

 

Example 3: Find the value of MXI + IX
Solution: MXI = 1011 and IX = 9
Now, add them: 1011 + 9 = 1020
In Roman numerals, 1020 = MXX

 

Example 4: Find the difference between ML (1050) and  XXX (30)
Solution: 1050 – 30 = 1020
Now convert 1020 to Roman numerals:
1000 + 20 = M + XX = MXX
Therefore, ML – XXX = MXX
