How MMCXLIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 100 | C |
| Tens | 40 | X (subtracted)L |
| Units | 4 | I (subtracted)V |
| Total | 2144 | MMCXLIV |
MMCXLIV is written one place at a time, from the largest to the smallest: MM (2000) + C (100) + XL (40) + IV (4) = 2144.
XL and IV are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMCXXXXIV
Why isn't 2144 written as MMCXXXXIV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2144 is MMCXLIV.
Wrong: MMCXLIIII
Why isn't 2144 written as MMCXLIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 2144 is MMCXLIV.
Wrong: MMCXXXXIIII
Why isn't 2144 written as MMCXXXXIIII?
No symbol can be repeated four times in a row, so XXXX and IIII are not used: 40 = XL, 4 = IV. Together they make MMCXLIV.
