How CCLXXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 200 | CC |
| Tens | 80 | LXXX |
| Units | 4 | I (subtracted)V |
| Total | 284 | CCLXXXIV |
CCLXXXIV is written one place at a time, from the largest to the smallest: CC (200) + LXXX (80) + IV (4) = 284.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: CCLXXXIIII
Why isn't 284 written as CCLXXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 284 is CCLXXXIV.
Wrong: CCXXCIV
Why isn't 284 written as CCXXCIV?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 284 is CCLXXXIV.
