How MCCXXIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 200 | CC |
| Tens | 20 | XX |
| Units | 4 | I (subtracted)V |
| Total | 1224 | MCCXXIV |
MCCXXIV is written one place at a time, from the largest to the smallest: M (1000) + CC (200) + XX (20) + IV (4) = 1224.
IV is the only subtraction: the I before the V takes away 1, so IV = 4.
Common mistakes
Wrong: MCCXXIIII
Why isn't 1224 written as MCCXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 1224 is MCCXXIV.
