500 in Roman numerals

500 = D

Working: D = 500

The number 500 is written as D in Roman numerals.

Roman numerals are built by adding symbol values together from largest to smallest: D = 500. 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, D is 1 symbol long. It is entirely additive: every symbol adds to the running total, with no smaller symbol standing before a larger one. No symbol repeats.

D is five hundred, and like V and L it is a five-anchor that never repeats: there is no DD for a thousand, because M covers it. That is why the numerals for 500 to 900 are built as D plus up to three Cs, then switch to CM at nine hundred.
