How MCDLXXXVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Tens | 80 | LXXX |
| Units | 7 | VII |
| Total | 1487 | MCDLXXXVII |
MCDLXXXVII is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + LXXX (80) + VII (7) = 1487.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MCCCCLXXXVII
Why isn't 1487 written as MCCCCLXXXVII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1487 is MCDLXXXVII.
Wrong: MCDXXCVII
Why isn't 1487 written as MCDXXCVII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 1487 is MCDLXXXVII.
