How MMCDXX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 20 | XX |
| Total | 2420 | MMCDXX |
MMCDXX is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + XX (20) = 2420.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMCCCCXX
Why isn't 2420 written as MMCCCCXX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2420 is MMCDXX.
