How MMMDCCLXXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 700 | DCC |
| Tens | 80 | LXXX |
| Units | 4 | I (subtracted)V |
| Total | 3784 | MMMDCCLXXXIV |
MMMDCCLXXXIV is written one place at a time, from the largest to the smallest: MMM (3000) + DCC (700) + LXXX (80) + IV (4) = 3784.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MMMDCCLXXXIIII
Why isn't 3784 written as MMMDCCLXXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 3784 is MMMDCCLXXXIV.
Wrong: MMMDCCXXCIV
Why isn't 3784 written as MMMDCCXXCIV?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 3784 is MMMDCCLXXXIV.
