How MMDCCCXCVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 800 | DCCC |
| Tens | 90 | X (subtracted)C |
| Units | 7 | VII |
| Total | 2897 | MMDCCCXCVII |
MMDCCCXCVII is written one place at a time, from the largest to the smallest: MM (2000) + DCCC (800) + XC (90) + VII (7) = 2897.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MMDCCCLXXXXVII
Why isn't 2897 written as MMDCCCLXXXXVII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 2897 is MMDCCCXCVII.
Wrong: MMCCMXCVII
Why isn't 2897 written as MMCCMXCVII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 2897 is MMDCCCXCVII.
