How MMMCCXLIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 200 | CC |
| Tens | 40 | X (subtracted)L |
| Units | 3 | III |
| Total | 3243 | MMMCCXLIII |
MMMCCXLIII is written one place at a time, from the largest to the smallest: MMM (3000) + CC (200) + XL (40) + III (3) = 3243.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMMCCXXXXIII
Why isn't 3243 written as MMMCCXXXXIII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3243 is MMMCCXLIII.
