How MCDXC is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Tens | 90 | X (subtracted)C |
| Total | 1490 | MCDXC |
MCDXC is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + XC (90) = 1490.
CD and XC are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MXD
Why isn't 1490 written as MXD?
X can only be subtracted from L and C, so XD (500 − 10) is not a valid pair. Write each place separately: M (1000) + CD (400) + XC (90) = MCDXC.
Wrong: MCCCCXC
Why isn't 1490 written as MCCCCXC?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1490 is MCDXC.
Wrong: MCDLXXXX
Why isn't 1490 written as MCDLXXXX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1490 is MCDXC.
