MMCCCXLV is written one place at a time, from the largest to the smallest: MM (2000) + CCC (300) + XL (40) + V (5) = 2345.

XL is the only subtraction: the X before the L takes away 10, so XL = 40.

Common mistakes

Wrong: MMCCCVL

Why isn't 2345 written as MMCCCVL?

V is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: MM (2000) + CCC (300) + XL (40) + V (5) = MMCCCXLV.

Wrong: MMCCCXXXXV

Why isn't 2345 written as MMCCCXXXXV?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2345 is MMCCCXLV.
