Example Calculations

Let’s look at a few example calculations to see how this tool works:

Example 1: Addition

  • Input:
    • First Roman numeral: X (10)
    • Second Roman numeral: V (5)
    • Operation: Add
  • Result:
    • Roman result: XV
    • Arabic result: 15

In this example, adding “X” (10) and “V” (5) gives “XV” in Roman numerals, which equals “15” in Arabic numerals.

Example 2: Subtraction

  • Input:
    • First Roman numeral: X (10)
    • Second Roman numeral: IV (4)
    • Operation: Subtract
  • Result:
    • Roman result: VI
    • Arabic result: 6

Here, subtracting “IV” (4) from “X” (10) gives “VI” (6) in Roman numerals, which equals “6” in Arabic numerals.

Example 3: Multiplication

  • Input:
    • First Roman numeral: V (5)
    • Second Roman numeral: III (3)
    • Operation: Multiply
  • Result:
    • Roman result: XV
    • Arabic result: 15

Multiplying “V” (5) by “III” (3) results in “XV” (15) in Roman numerals, equivalent to “15” in Arabic numerals.

Example 4: Division

  • Input:
    • First Roman numeral: X (10)
    • Second Roman numeral: II (2)
    • Operation: Divide
  • Result:
    • Roman result: V
    • Arabic result: 5

Dividing “X” (10) by “II” (2) gives “V” (5) in Roman numerals, which equals “5” in Arabic numerals.
