How MMMCMLXXXVI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 80 | LXXX |
| Units | 6 | VI |
| Total | 3986 | MMMCMLXXXVI |
MMMCMLXXXVI is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + LXXX (80) + VI (6) = 3986.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMMDCCCCLXXXVI
Why isn't 3986 written as MMMDCCCCLXXXVI?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3986 is MMMCMLXXXVI.
Wrong: MMMCMXXCVI
Why isn't 3986 written as MMMCMXXCVI?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 3986 is MMMCMLXXXVI.
