How MMMDCCCLXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 800 | DCCC |
| Tens | 60 | LX |
| Units | 4 | I (subtracted)V |
| Total | 3864 | MMMDCCCLXIV |
MMMDCCCLXIV is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + LX (60) + IV (4) = 3864.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MMMDCCCLXIIII
Why isn't 3864 written as MMMDCCCLXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 3864 is MMMDCCCLXIV.
Wrong: MMMCCMLXIV
Why isn't 3864 written as MMMCCMLXIV?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3864 is MMMDCCCLXIV.
