MMMDCXLIX is written one place at a time, from the largest to the smallest: MMM (3000) + DC (600) + XL (40) + IX (9) = 3649.

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

Common mistakes

Wrong: MMMDCIL

Why isn't 3649 written as MMMDCIL?

I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: MMM (3000) + DC (600) + XL (40) + IX (9) = MMMDCXLIX.

Wrong: MMMDCXXXXIX

Why isn't 3649 written as MMMDCXXXXIX?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3649 is MMMDCXLIX.

Wrong: MMMDCXLVIIII

Why isn't 3649 written as MMMDCXLVIIII?

A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3649 is MMMDCXLIX.
