How MMMCDXXVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 20 | XX |
| Units | 7 | VII |
| Total | 3427 | MMMCDXXVII |
MMMCDXXVII is written one place at a time, from the largest to the smallest: MMM (3000) + CD (400) + XX (20) + VII (7) = 3427.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMMCCCCXXVII
Why isn't 3427 written as MMMCCCCXXVII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3427 is MMMCDXXVII.
