How MDCCLXXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 700 | DCC |
| Tens | 80 | LXXX |
| Units | 4 | I (subtracted)V |
| Total | 1784 | MDCCLXXXIV |
MDCCLXXXIV is written one place at a time, from the largest to the smallest: M (1000) + DCC (700) + LXXX (80) + IV (4) = 1784.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MDCCLXXXIIII
Why isn't 1784 written as MDCCLXXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 1784 is MDCCLXXXIV.
Wrong: MDCCXXCIV
Why isn't 1784 written as MDCCXXCIV?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 1784 is MDCCLXXXIV.
