Basic Rules to Write Roman Numerals

• Repetition Rule: A symbol can be repeated only 3 times.
  Example: XX = 20, CC = 200
• A symbol is added to itself if repeated.
  Example: III = 3, XXX = 30
• Subtractive Rule: If a smaller symbol precedes a larger one, we subtract.
  Example: IX = 10 - 1 = 9
• Additive Rule: If a smaller symbol comes after a bigger one, we add.
  Example: VI = 5 + 1 = 6
• Symbols V (5), L (50), and D (500) are never repeated and never subtracted.
  I can be subtracted only from V and X and X can be subtracted only from L, C, and M.

 

Solved Examples on 115 in Roman Numerals

Example 1: Write the sum of C (100) and XV (15) in Roman numerals.

Solution: C = 100, XV = 15

100 + 15 = 115

Roman numeral = CXV

 

Example 2: Convert 90 + 25 to Roman numerals.

Solution: 90 = XC, 25 = XXV

XC + XXV = CXV (which equals 115)

 

Example 3: Subtract V (5) from CXX (120).

Solution: 120 - 5 = 115

Roman numeral = CXV

 

Example 4: A wall inscription shows the year written as CXV. What number does it represent?

Solution: CXV = 100 + 10 + 5 = 115
