How MMMCMXLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 40 | X (subtracted)L |
| Units | 9 | I (subtracted)X |
| Total | 3949 | MMMCMXLIX |
MMMCMXLIX is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + XL (40) + IX (9) = 3949.
CM, XL, and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMMCMIL
Why isn't 3949 written as MMMCMIL?
I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: MMM (3000) + CM (900) + XL (40) + IX (9) = MMMCMXLIX.
Wrong: MMMDCCCCXLIX
Why isn't 3949 written as MMMDCCCCXLIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3949 is MMMCMXLIX.
Wrong: MMMCMXXXXIX
Why isn't 3949 written as MMMCMXXXXIX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3949 is MMMCMXLIX.
