MMMCMLXIX is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + LX (60) + IX (9) = 3969.

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

Common mistakes

Wrong: MMMDCCCCLXIX

Why isn't 3969 written as MMMDCCCCLXIX?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3969 is MMMCMLXIX.

Wrong: MMMCMLXVIIII

Why isn't 3969 written as MMMCMLXVIIII?

A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3969 is MMMCMLXIX.

Wrong: MMMDCCCCLXVIIII

Why isn't 3969 written as MMMDCCCCLXVIIII?

No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make MMMCMLXIX.
