How CCLIV is built
Roman numerals are written one decimal place at a time, largest first.
- CChundreds · 2C written 2 times: 2 × 100 = 200.
- Ltens · 5L is 50.
- IVones · 4I before V means 5 − 1 = 4. This saves writing IIII.
200 + 50 + 4 = 254
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 CCLIIII (7 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CCLIV (5 letters) is the standard.
