MMCDXV is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + X (10) + V (5) = 2415.

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

Common mistakes

Wrong: MMCCCCXV

Why isn't 2415 written as MMCCCCXV?

A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2415 is MMCDXV.
