MDCXCIX is written one place at a time, from the largest to the smallest: M (1000) + DC (600) + XC (90) + IX (9) = 1699.

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

Common mistakes

Wrong: MDCIC

Why isn't 1699 written as MDCIC?

I can only be subtracted from V and X, so IC (100 − 1) is not a valid pair. Write each place separately: M (1000) + DC (600) + XC (90) + IX (9) = MDCXCIX.

Wrong: MDCLXXXXIX

Why isn't 1699 written as MDCLXXXXIX?

A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1699 is MDCXCIX.

Wrong: MDCXCVIIII

Why isn't 1699 written as MDCXCVIIII?

A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1699 is MDCXCIX.
