How MCCCXLV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 300 | CCC |
| Tens | 40 | X (subtracted)L |
| Units | 5 | V |
| Total | 1345 | MCCCXLV |
MCCCXLV is written one place at a time, from the largest to the smallest: M (1000) + CCC (300) + XL (40) + V (5) = 1345.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MCCCVL
Why isn't 1345 written as MCCCVL?
V is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: M (1000) + CCC (300) + XL (40) + V (5) = MCCCXLV.
Wrong: MCCCXXXXV
Why isn't 1345 written as MCCCXXXXV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 1345 is MCCCXLV.
