How MMCMLXXXI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 80 | LXXX |
| Units | 1 | I |
| Total | 2981 | MMCMLXXXI |
MMCMLXXXI is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + LXXX (80) + I (1) = 2981.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMDCCCCLXXXI
Why isn't 2981 written as MMDCCCCLXXXI?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2981 is MMCMLXXXI.
Wrong: MMCMXXCI
Why isn't 2981 written as MMCMXXCI?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 2981 is MMCMLXXXI.
