25 in Roman numerals

XXV

25 = XXV

Working: X = 10, X = 10, V = 5

The number 25 is written as XXV in Roman numerals.

Roman numerals are built by adding symbol values together from largest to smallest: X = 10, X = 10, V = 5. Where a smaller symbol appears before a larger one — as in IV for 4 or IX for 9 — it is subtracted rather than added, which keeps the notation short.

Structurally, XXV is 3 symbols long. It is entirely additive: every symbol adds to the running total, with no smaller symbol standing before a larger one. The longest run is 2 identical symbols.

XXV is twenty plus five, and it is a common numeral in anniversary and jubilee contexts, where a twenty-fifth is the silver milestone. Its compactness — three symbols for a two-digit number — is part of why it appears in engraving and commemorative use.
