How MMDCLXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 600 | DC |
| Tens | 60 | LX |
| Units | 4 | I (subtracted)V |
| Total | 2664 | MMDCLXIV |
MMDCLXIV is written one place at a time, from the largest to the smallest: MM (2000) + DC (600) + LX (60) + IV (4) = 2664.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MMDCLXIIII
Why isn't 2664 written as MMDCLXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 2664 is MMDCLXIV.
