How MMCMLXXX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 80 | LXXX |
| Total | 2980 | MMCMLXXX |
MMCMLXXX is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + LXXX (80) = 2980.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMDCCCCLXXX
Why isn't 2980 written as MMDCCCCLXXX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2980 is MMCMLXXX.
Wrong: MMCMXXC
Why isn't 2980 written as MMCMXXC?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 2980 is MMCMLXXX.
