MMDCCXCI is written one place at a time, from the largest to the smallest: MM (2000) + DCC (700) + XC (90) + I (1) = 2791.

XC is the only subtraction: the X before the C takes away 10, so XC = 90.

Common mistakes

Wrong: MMDCCLXXXXI

Why isn't 2791 written as MMDCCLXXXXI?

A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 2791 is MMDCCXCI.
