How DCCCXXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 800 | DCCC |
| Tens | 30 | XXX |
| Units | 4 | I (subtracted)V |
| Total | 834 | DCCCXXXIV |
DCCCXXXIV is written one place at a time, from the largest to the smallest: DCCC (800) + XXX (30) + IV (4) = 834.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: DCCCXXXIIII
Why isn't 834 written as DCCCXXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 834 is DCCCXXXIV.
Wrong: CCMXXXIV
Why isn't 834 written as CCMXXXIV?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 834 is DCCCXXXIV.
