What Are Roman Numerals?
Roman numerals are a number system that originated in ancient Rome. They use combinations of letters from the Latin alphabet to represent values. The numerals include I, V, X, L, C, D, and M, standing respectively for 1, 5, 10, 50, 100, 500, and 1,000.
After 10, Roman numerals go XI for 11, XII for 12, XIII for 13, and continue up to XX for 20. The table below shows the most commonly used Roman numerals for basic numbers.

History of Roman Numerals
Roman numerals were used in ancient Rome and throughout the Roman Empire. They were the standard way of writing numbers until the adoption of the more efficient Arabic numeral system (the numbers we use today). The Romans originally used these numerals for trade, military, and administrative purposes.
Uses of Roman Numerals
Today, Roman numerals are not used for everyday calculations but have several specific uses. They are often used to:
- Number the chapters and volumes of books.
- Mark hours on clocks and watches.
- Identify the annual Super Bowl games, as in Super Bowl LV.
- Denote centuries or significant historical years, such as in movies or monument inscriptions.
Importance of Roman Numerals
Although they are no longer necessary for most numeric functions, Roman numerals still hold cultural and historical significance. They provide a link to the past and are used in contexts where tradition or visual impact is important. They also serve educational purposes in schools to teach about the history of numbers and to improve problem-solving skills.
