Total2124MMCXXIV

MMCXXIV is written one place at a time, from the largest to the smallest: MM (2000) + C (100) + XX (20) + IV (4) = 2124.

IV is the only subtraction: the I before the V takes away 1, so IV = 4.

Common mistakes

Wrong: MMCXXIIII

Why isn't 2124 written as MMCXXIIII?

A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 2124 is MMCXXIV.
