How MDCCXCVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 700 | DCC |
| Tens | 90 | X (subtracted)C |
| Units | 7 | VII |
| Total | 1797 | MDCCXCVII |
MDCCXCVII is written one place at a time, from the largest to the smallest: M (1000) + DCC (700) + XC (90) + VII (7) = 1797.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MDCCLXXXXVII
Why isn't 1797 written as MDCCLXXXXVII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1797 is MDCCXCVII.
