How CCCXIV is built
Roman numerals are written one decimal place at a time, largest first.
- CCChundreds · 3C written 3 times: 3 × 100 = 300.
- Xtens · 1X is 10.
- IVones · 4I before V means 5 − 1 = 4. This saves writing IIII.
300 + 10 + 4 = 314
The pair IV 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 CCCXIIII (8 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CCCXIV (6 letters) is the standard.
