How MMCMXLV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 40 | X (subtracted)L |
| Units | 5 | V |

MMCMXLV is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + XL (40) + V (5) = 2945.
CM and XL are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMCMVL
Why isn't 2945 written as MMCMVL?
V is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: MM (2000) + CM (900) + XL (40) + V (5) = MMCMXLV.
Wrong: MMDCCCCXLV
Why isn't 2945 written as MMDCCCCXLV?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2945 is MMCMXLV.
Wrong: MMCMXXXXV
Why isn't 2945 written as MMCMXXXXV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2945 is MMCMXLV.
