Basic Rules for Writing Roman Numerals

All Roman numerals are written by arranging the same Latin letters in a different order.  Each numeral represents a unique value depending on the way letters are arranged. To understand these patterns, we need to learn the basic rules of Roman numerals. Some of these basic rules for writing Roman numerals are listed below:

• Rule 1: When smaller numerals follow larger ones, you add them.
  Example: VI = 5 + 1 = 6
  
  

• Rule 2: When a smaller numeral appears before a larger one, you subtract it.
  Example: IX = 10 - 1 = 9
  
  

• Rule 3: Symbols like V (5), L (50), and D (500) are never repeated.
  
  

• Rule 4: Symbols like I, X, C, and M can be repeated up to three times.
