CCXXXVI

CCXXXVI is the Roman numeral representation of the integer two hundred thirty‑six. The symbol consists of the additive combination of C (100) repeated twice for 200, followed by the Diminutive subtractive notation of XXX (30) and VI (6). In Roman numerals, the digits C, L (50), X (10), V (5), and I (1) are used, with larger values placed before smaller values to indicate addition. The numeral may be read aloud as “two‑hundred thirty‑six.”

The number 236 itself has modest mathematical properties. It is an even composite integer, factorable as 2 × 2 × 59. In the domain of number theory, it is neither prime nor a perfect square. It belongs to the class of integers that are the product of the square of 2 and a prime. Additionally, 236 is the 14th composite number that is the sum of two consecutive squares, with 15² + 16² = 225 + 256 = 481, showing its relationship in certain quadratic sequences.

Roman numerals have been used historically for centuries in Europe to denote dates, document numbers, and the numbering of chapters or buildings. The modern Unicode standard includes characters for Roman numerals, allowing CCXXXVI to appear in digital texts. In contemporary contexts, the numeral may appear on clock faces, in inscriptions on monuments, or as a symbolic representation in cartographic or historical documentation indicating the year 236 AD or 236 CE, or in commemorative plaques referencing the 236th edition of a recurring event.

The usage of CCXXXVI and related numerals continues in educational settings where students learn about ancient numbering systems, and in heritage preservation where accurate representation of old inscriptions is essential.
