How DXLIII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 500 | D |
| Tens | 40 | X (subtracted)L |
| Units | 3 | III |
| Total | 543 | DXLIII |
DXLIII is written one place at a time, from the largest to the smallest: D (500) + XL (40) + III (3) = 543.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: DXXXXIII
Why isn't 543 written as DXXXXIII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 543 is DXLIII.
