How MCDXCVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Tens | 90 | X (subtracted)C |
| Units | 7 | VII |
| Total | 1497 | MCDXCVII |
MCDXCVII is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + XC (90) + VII (7) = 1497.
CD and XC are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MCCCCXCVII
Why isn't 1497 written as MCCCCXCVII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1497 is MCDXCVII.
Wrong: MCDLXXXXVII
Why isn't 1497 written as MCDLXXXXVII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1497 is MCDXCVII.
Wrong: MCCCCLXXXXVII
Why isn't 1497 written as MCCCCLXXXXVII?
No symbol can be repeated four times in a row, so CCCC and LXXXX are not used: 400 = CD, 90 = XC. Together they make MCDXCVII.
