MCDXX is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + XX (20) = 1420.

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

Common mistakes

Wrong: MCCCCXX

Why isn't 1420 written as MCCCCXX?

A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1420 is MCDXX.
