How MMCMLXXXVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 80 | LXXX |
| Units | 7 | VII |
| Total | 2987 | MMCMLXXXVII |
MMCMLXXXVII is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + LXXX (80) + VII (7) = 2987.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMDCCCCLXXXVII
Why isn't 2987 written as MMDCCCCLXXXVII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2987 is MMCMLXXXVII.
Wrong: MMCMXXCVII
Why isn't 2987 written as MMCMXXCVII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 2987 is MMCMLXXXVII.
