CXCVI

CXCVI is the Roman numeral representing the number 196. It is formed by combining C (100), XC (90), and VI (6). This uses subtractive notation, where the smaller numeral X placed before C indicates 10 less than 100, yielding 90.

In modern contexts, CXCVI may appear in inscriptions, lists, chapter headings, or as a designation where Roman numerals are preferred, such as to indicate volumes or regnal numbers. When used as a year, the value would correspond to 196 CE (196 AD) in the Common Era dating convention; if used for a year in the BCE era, it would denote 196 BCE, typically labeled with the BCE designation.

Numeric properties of 196 include being a perfect square (14 squared). Its prime factorization is 2^2 × 7^2, making it a composite number. It is divisible by 1, 2, 4, 7, 14, 28, 49, 98, and 196. The sum of its digits is 16, and it is an even number.

In typography and encoding, CXCVI is written using the standard Latin letters C, X, V, and I. It serves as a representative example of Roman numeral notation, illustrating how subtractive and additive elements combine to express a specific integer in historical and contemporary contexts.
