MDCCCXXX is written one place at a time, from the largest to the smallest: M (1000) + DCCC (800) + XXX (30) = 1830.

Common mistakes

Wrong: MCCMXXX

Why isn't 1830 written as MCCMXXX?

Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 1830 is MDCCCXXX.
