How MDCCCXC is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 800 | DCCC |
| Tens | 90 | X (subtracted)C |
| Total | 1890 | MDCCCXC |
MDCCCXC is written one place at a time, from the largest to the smallest: M (1000) + DCCC (800) + XC (90) = 1890.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MDCCCLXXXX
Why isn't 1890 written as MDCCCLXXXX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1890 is MDCCCXC.
Wrong: MCCMXC
Why isn't 1890 written as MCCMXC?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 1890 is MDCCCXC.
