How CCXXXIX is built
Roman numerals are written one decimal place at a time, largest first.
- CChundreds · 2C written 2 times: 2 × 100 = 200.
- XXXtens · 3X written 3 times: 3 × 10 = 30.
- IXones · 9I before X means 10 − 1 = 9. This saves writing VIIII.
200 + 30 + 9 = 239
The pair IX 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 CCXXXVIIII (10 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CCXXXIX (7 letters) is the standard.
