CLIV is written one place at a time, from the largest to the smallest: C (100) + L (50) + IV (4) = 154.

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

Common mistakes

Wrong: CLIIII

Why isn't 154 written as CLIIII?

A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 154 is CLIV.
