Roman numerals are a system of numerical notation used in ancient Rome. They are based on seven symbols: I, V, X, L, C, D, and M. The value of each symbol is determined by its position within the number. For example, I represents one, V represents five, and X represents ten. The letter X can be used to create larger numbers. When X is placed before a symbol that represents a smaller number, it subtracts the value of the smaller number from the value of the larger number. For example, IX represents nine, because the X subtracts one from the value of the I. When X is placed after a symbol that represents a larger number, it adds the value of the smaller number to the value of the larger number. For example, XI represents eleven, because the X adds one to the value of the I.
