MMDCCLXXIX is written one place at a time, from the largest to the smallest: MM (2000) + DCC (700) + LXX (70) + IX (9) = 2779.

IX is the only subtraction: the I before the X takes away 1, so IX = 9.

Common mistakes

Wrong: MMDCCLXXVIIII

Why isn't 2779 written as MMDCCLXXVIIII?

A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2779 is MMDCCLXXIX.
