CCCLXXIX is written one place at a time, from the largest to the smallest: CCC (300) + LXX (70) + IX (9) = 379.

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

Common mistakes

Wrong: CCCLXXVIIII

Why isn't 379 written as CCCLXXVIIII?

A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 379 is CCCLXXIX.
