How MMDCCCXLIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 800 | DCCC |
| Tens | 40 | X (subtracted)L |
| Units | 3 | III |
| Total | 2843 | MMDCCCXLIII |
MMDCCCXLIII is written one place at a time, from the largest to the smallest: MM (2000) + DCCC (800) + XL (40) + III (3) = 2843.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMDCCCXXXXIII
Why isn't 2843 written as MMDCCCXXXXIII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2843 is MMDCCCXLIII.
Wrong: MMCCMXLIII
Why isn't 2843 written as MMCCMXLIII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 2843 is MMDCCCXLIII.
