How to Convert Roman Numerals to Arabic Numerals
To convert Roman numerals like LXIV into Arabic numerals, follow these steps:
Step 1: Identify the Values of Each Letter
Each Roman numeral has a fixed value:
- L = 50
- X = 10
- I = 1
- V = 5
Step 2: Apply Addition and Subtraction Rules
Roman numerals follow two basic rules:
- If a smaller numeral comes before a larger one, subtract it.
