How MDCXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 600 | DC |
| Tens | 20 | XX |
| Units | 4 | I (subtracted)V |
| Total | 1624 | MDCXXIV |
MDCXXIV is written one place at a time, from the largest to the smallest: M (1000) + DC (600) + XX (20) + IV (4) = 1624.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MDCXXIIII
Why isn't 1624 written as MDCXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 1624 is MDCXXIV.
