How XLIII is formed
| Place | Value | Symbols |
|---|---|---|
| Tens | 40 | X (subtracted)L |
| Units | 3 | III |
| Total | 43 | XLIII |
XLIII is written one place at a time, from the largest to the smallest: XL (40) + III (3) = 43.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: XXXXIII
Why isn't 43 written as XXXXIII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 43 is XLIII.
