How MDXCVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 500 | D |
| Tens | 90 | X (subtracted)C |
| Units | 7 | VII |
| Total | 1597 | MDXCVII |
MDXCVII is written one place at a time, from the largest to the smallest: M (1000) + D (500) + XC (90) + VII (7) = 1597.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MDLXXXXVII
Why isn't 1597 written as MDLXXXXVII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1597 is MDXCVII.
