MXXXI

MXXXI is the Roman numeral for the integer 1031. It is formed by combining the letters M (1000), XXX (30), and I (1) to yield 1000 + 30 + 1. This additive arrangement is a standard way to write numbers in Roman numerals, without employing subtractive notation in this case.

In historical practice, Roman numerals were used to indicate years, monarchs, or enumerations on inscriptions and manuscripts. Therefore, MXXXI can be used to denote the year 1031 CE in a historical document, or to label editions or volumes in modern texts when a classical style is desired.

From a numerical perspective, 1031 is a prime number, a property it has as a positive integer. As such, it has no positive divisors other than 1 and itself.

In typographic and computing contexts, MXXXI is simply a sequence of Latin letters representing a number; there is no dedicated symbol separate from the standard Latin alphabet for Roman numerals. It can be rendered in any font that supports Latin characters, and may appear in clocks, inscriptions, or lists that employ classical numeral styles.
