How DXLVII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 500 | D |
| Tens | 40 | X (subtracted)L |
| Units | 7 | VII |
| Total | 547 | DXLVII |
DXLVII is written one place at a time, from the largest to the smallest: D (500) + XL (40) + VII (7) = 547.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: DXXXXVII
Why isn't 547 written as DXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 547 is DXLVII.
