Roman Numerals are a way of writing numbers that was used a long time ago in ancient Rome and throughout the Roman Empire. Even today, we still use Roman Numerals in some places, like on clock faces, in the names of certain sports games, and in the credits of movies. Although there is another way of writing numbers that is more commonly used today, Roman Numerals still hold importance as part of our history and culture.
Roman numerals a system of symbols used to represent numbers, originated in ancient Rome about 2,500 years ago. The ancient Romans used their fingers to count, but eventually replaced them with symbols to simplify record keeping.
Roman numerals remained popular throughout Europe until the Late Middle Ages, when they were gradually replaced by Arabic numerals. Roman numerals differ from Arabic numerals in that they don't have a symbol for zero and don't follow the decimal system.
