How MCXLIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 100 | C |
| Tens | 40 | X (subtracted)L |
| Units | 3 | III |
| Total | 1143 | MCXLIII |
MCXLIII is written one place at a time, from the largest to the smallest: M (1000) + C (100) + XL (40) + III (3) = 1143.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MCXXXXIII
Why isn't 1143 written as MCXXXXIII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 1143 is MCXLIII.
