What are some popular applications for Roman numerals?

In everyday life, Roman numerals are commonly used on clock faces, chapter numbering and copyrighting in books, pharmaceutical prescriptions, and numbered lists. For the dating of movies and television shows, dates are sometimes presented in Roman numerals. They are also used during some sporting events, including as the Olympics, the Super Bowl, and wrestling matches.

Converting Roman numerals

When using Roman numerals, it's vital to remember not just the digits themselves, but also the sequence in which they appear. When a smaller number appears in front of a larger number, for example, it signifies that the smaller number should be subtracted from the larger one. If a lower number follows after it, it is added.
