What Are Roman Numerals and How Do They Work?
Roman numerals have been used since antiquity and are still prevalent in various contexts today. They are often seen in the titles of monarchs and popes, on clock faces, and in the enumeration of book chapters or movie sequels. Here’s a brief overview of how Roman numerals work:
