Roman numerals are a numeral system originating from ancient Rome, and are based on certain letters of the alphabet which are combined according to rules to signify values.

There are seven basic symbols in the Roman numeral system: I, V, X, L, C, D, and M. Each symbol represents a different number, as follows:

  • L: 50
  • C: 100
  • D: 500
  • M: 1000

The value of Roman numerals is based on the principle that placing a smaller numeral to the left of a larger numeral means subtraction, while placing it to the right means addition. For example, IV means 4 (5-1), while VI means 6 (5+1).
