Total3430MMMCDXXX

MMMCDXXX is written one place at a time, from the largest to the smallest: MMM (3000) + CD (400) + XXX (30) = 3430.

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

Common mistakes

Wrong: MMMCCCCXXX

Why isn't 3430 written as MMMCCCCXXX?

A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3430 is MMMCDXXX.
