How MDCLIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 600 | DC |
| Tens | 50 | L |
| Units | 4 | I (subtracted)V |
| Total | 1654 | MDCLIV |
MDCLIV is written one place at a time, from the largest to the smallest: M (1000) + DC (600) + L (50) + IV (4) = 1654.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MDCLIIII
Why isn't 1654 written as MDCLIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 1654 is MDCLIV.
