How DCCXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 700 | DCC |
| Tens | 20 | XX |
| Units | 4 | I (subtracted)V |
| Total | 724 | DCCXXIV |
DCCXXIV is written one place at a time, from the largest to the smallest: DCC (700) + XX (20) + IV (4) = 724.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: DCCXXIIII
Why isn't 724 written as DCCXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 724 is DCCXXIV.
