CCCXXII

CCCXXII is the Roman numeral representation of the Arabic number three hundred twenty‑two. It is formed by combining the symbols C (100) and M (1000) in subtraction notation, with three C’s adding to 300, and the remaining XXII adding 22, giving a total of 322. In classical Roman numeration, numbers above one hundred are traditionally written by placing the 100’s digit first, followed by the remainder, which is why CCCXXII is the standard form for 322.

Historically, the number 322 has appeared in several contexts. In the Roman military, units were often numbered with Roman numerals, so a unit designated “CCCXXII” would have been the 322nd regiment or cohort in a particular legion or army list. In antiquity, 322 was also used as a year designation; the year 322 BC, for example, was marked in Roman calendars as a notable period of political change in the Greek world. In the New Testament period, 322 AD is associated with the reign of Emperor Galerius and important administrative reforms.

In modern usage, 322 is a common designation in transportation, such as U.S. State Route 322 in several states, and in telecommunications, the letters “CCCXXII” may be seen as an alphanumeric representation in serial numbering systems. Mathematically, 322 is an even composite number, equal to 2 × 161, and it can be expressed as the sum of 100, 100, and 122 or as a near‑prime in various factorization contexts.

Overall, CCCXXII functions primarily as the Roman numeral signifier for the integer 322, with its appearances reflecting the continued legacy of Roman numeration in modern numbering systems.
