How MMDCLXXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 600 | DC |
| Tens | 80 | LXXX |
| Units | 4 | I (subtracted)V |
| Total | 2684 | MMDCLXXXIV |
MMDCLXXXIV is written one place at a time, from the largest to the smallest: MM (2000) + DC (600) + LXXX (80) + IV (4) = 2684.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MMDCLXXXIIII
Why isn't 2684 written as MMDCLXXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 2684 is MMDCLXXXIV.
Wrong: MMDCXXCIV
Why isn't 2684 written as MMDCXXCIV?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 2684 is MMDCLXXXIV.
