How MDCCXCVIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 700 | DCC |
| Tens | 90 | X (subtracted)C |
| Units | 8 | VIII |
| Total | 1798 | MDCCXCVIII |
MDCCXCVIII is written one place at a time, from the largest to the smallest: M (1000) + DCC (700) + XC (90) + VIII (8) = 1798.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MDCCLXXXXVIII
Why isn't 1798 written as MDCCLXXXXVIII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1798 is MDCCXCVIII.
Wrong: MDCCXCIIX
Why isn't 1798 written as MDCCXCIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 1798 is MDCCXCVIII.
