MMCDXXXVIII is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + XXX (30) + VIII (8) = 2438.

CD is the only subtraction: the C before the D takes away 100, so CD = 400.

Common mistakes

Wrong: MMCCCCXXXVIII

Why isn't 2438 written as MMCCCCXXXVIII?

A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2438 is MMCDXXXVIII.

Wrong: MMCDXXXIIX

Why isn't 2438 written as MMCDXXXIIX?

Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 2438 is MMCDXXXVIII.
