MMMCDLI is written one place at a time, from the largest to the smallest: MMM (3000) + CD (400) + L (50) + I (1) = 3451.

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

Common mistakes

Wrong: MMMCCCCLI

Why isn't 3451 written as MMMCCCCLI?

A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3451 is MMMCDLI.
