1955 digit by digit
| Place | Value | Numeral | Rule used |
|---|---|---|---|
| thousands | 1000 | M | one symbol |
| hundreds | 900 | CM | subtractive: one symbol before the ten symbol |
| tens | 50 | L | the five symbol on its own |
| ones | 5 | V | the five symbol on its own |
Check MCMLV by reading it back
Reading MCMLV from left to right and adding the pieces: M = 1000, CM = 900, L = 50, V = 5. Together that is 1000 + 900 + 50 + 5 = 1955, so MCMLV and 1955 match.
Mistakes to avoid with MCMLV
- Do not write the 4s and 9s additively. 1955 uses subtractive pairs (
CMfor 900), not strings like IIII or VIIII. - Only I, X and C may be placed before a larger symbol to subtract, so MCMLV never contains forms such as VX or LC.
- Read MCMLV as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
