MMMCMXLII is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + XL (40) + II (2) = 3942.

CM and XL are subtractive pairs: in each one the smaller symbol comes first and is taken away.

Common mistakes

Wrong: MMMDCCCCXLII

Why isn't 3942 written as MMMDCCCCXLII?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3942 is MMMCMXLII.

Wrong: MMMCMXXXXII

Why isn't 3942 written as MMMCMXXXXII?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3942 is MMMCMXLII.

Wrong: MMMDCCCCXXXXII

Why isn't 3942 written as MMMDCCCCXXXXII?

No symbol can be repeated four times in a row, so DCCCC and XXXX are not used: 900 = CM, 40 = XL. Together they make MMMCMXLII.
