How MMCDXXX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 30 | XXX |
| Total | 2430 | MMCDXXX |
MMCDXXX is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + XXX (30) = 2430.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMCCCCXXX
Why isn't 2430 written as MMCCCCXXX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2430 is MMCDXXX.
