CMLIX
959 is written CMLIX in Roman numerals. That is 3 symbol groups added together, reading left to right from the largest value down.
How it breaks down
| Group | Value | Subtraction | Running total |
|---|---|---|---|
| CM | 900 | M − C | 900 |
| L | 50 | — | 950 |
| IX | 9 | X − I | 959 |
Why the smaller symbol comes first
CMLIX uses subtractive notation in 2 places: CM means M minus C, or 900; IX means X minus I, or 9. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.
Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.
