How MCDXXIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Tens | 20 | XX |
| Units | 3 | III |
| Total | 1423 | MCDXXIII |
MCDXXIII is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + XX (20) + III (3) = 1423.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MCCCCXXIII
Why isn't 1423 written as MCCCCXXIII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1423 is MCDXXIII.
