How MDCCCXLIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 800 | DCCC |
| Tens | 40 | X (subtracted)L |
| Units | 3 | III |
| Total | 1843 | MDCCCXLIII |
MDCCCXLIII is written one place at a time, from the largest to the smallest: M (1000) + DCCC (800) + XL (40) + III (3) = 1843.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MDCCCXXXXIII
Why isn't 1843 written as MDCCCXXXXIII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 1843 is MDCCCXLIII.
Wrong: MCCMXLIII
Why isn't 1843 written as MCCMXLIII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 1843 is MDCCCXLIII.
