MMMCDXLV is written one place at a time, from the largest to the smallest: MMM (3000) + CD (400) + XL (40) + V (5) = 3445.
CD and XL are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMMCDVL
Why isn't 3445 written as MMMCDVL?
V is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: MMM (3000) + CD (400) + XL (40) + V (5) = MMMCDXLV.
Wrong: MMMCCCCXLV
Why isn't 3445 written as MMMCCCCXLV?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3445 is MMMCDXLV.
Wrong: MMMCDXXXXV
Why isn't 3445 written as MMMCDXXXXV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3445 is MMMCDXLV.
