How CMLVIII is built
Roman numerals are written one decimal place at a time, largest first.
- CMhundreds · 9C before M means 1,000 − 100 = 900. This saves writing DCCCC.
- Ltens · 5L is 50.
- VIIIones · 8V (5) plus III (3) makes 8.
900 + 50 + 8 = 958
The pair CM uses subtraction: a smaller letter before a larger one is taken away from it. Only six pairs work this way: IV, IX, XL, XC, CD and CM. More on subtraction
Mistakes to avoid
- Not DCCCCLVIII (10 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CMLVIII (7 letters) is the standard.
