MMMCCXXIX

MMMCCXXIX is the Roman numeral for the number 3229. In Roman numerals, thousands are written with M for 1000, so MMM equals 3000; CC is 200; XX is 20; and IX represents 9 via subtractive notation. The total is 3000 + 200 + 20 + 9 = 3229.

The numeral exemplifies typical Roman conventions: one often uses additive symbols for larger values, with subtractive pairs such as IV (4) and IX (9) used to avoid four consecutive characters. Here IX is at the end. The maximum common form without using overbar notation is 3999, so MMMCCXXIX is valid in standard Roman numerals.

In modern contexts, MMMCCXXIX may appear in numbering systems, outlines, monarch regnal numbering, or clock faces and monuments. It is not used as frequently as smaller numbers but serves as a convenient example of the numeral system's structure. The corresponding Arabic numeral is 3229.

Mathematical note: 3229 is a prime number; no divisors were found among the primes up to 53, which covers the square root of 3229. Its primality, like that of many integers, is a straightforward check by trial division for such small factors.
