How MCDXXII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Tens | 20 | XX |
| Units | 2 | II |
| Total | 1422 | MCDXXII |
MCDXXII is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + XX (20) + II (2) = 1422.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MCCCCXXII
Why isn't 1422 written as MCCCCXXII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1422 is MCDXXII.
