How MMMDCCCXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 800 | DCCC |
| Tens | 20 | XX |
| Units | 4 | I (subtracted)V |
| Total | 3824 | MMMDCCCXXIV |
MMMDCCCXXIV is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + XX (20) + IV (4) = 3824.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MMMDCCCXXIIII
Why isn't 3824 written as MMMDCCCXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 3824 is MMMDCCCXXIV.
Wrong: MMMCCMXXIV
Why isn't 3824 written as MMMCCMXXIV?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3824 is MMMDCCCXXIV.
