CXXIII

CXXIII is the Roman numeral for the number 123. It is formed by combining the symbols C (100), XX (20), and III (3) in additive notation, with no subtractive component involved in this particular numeral.

Roman numerals originated in ancient Rome and are still used today in various contexts for stylistic or traditional reasons. The system uses the letters I, V, X, L, C, D, and M, with specific values and placement rules. Subtractive notation exists for certain values (such as IV for 4 or IX for 9), but CXXIII does not employ subtraction.

In modern usage, CXXIII may appear as a designation in texts, catalogs, or model identifiers where Roman numerals are preferred. It can also be encountered in education, art, architecture, or media as a representation of the number 123 in Roman form. While not tied to any particular organization, standard, or event by itself, the string CXXIII functions as a numeric label equivalent to the decimal 123. When seen in lists or indices, it typically indicates the 123rd item or position in a sequence.
