MCXXI

MCXXI is the Roman numeral representation of the number 1121. Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers are expressed in Roman numerals using combinations of letters from the Latin alphabet. The Roman numeral system uses seven symbols, each with a fixed integer value. These symbols are I (1), V (5), X (10), L (50), C (100), D (500), and M (1,000). To form a numeral, the symbols are combined and their values are added together. If a symbol of lower value appears before one of higher value, its value is subtracted. For example, the numeral MCXXI is composed of M (1000), C (100), X (10), and I (1). The numeral MCXXI represents the number 1121, which is the sum of these values.
