How CCCLXXIX is built
Roman numerals are written one decimal place at a time, largest first.
- CCChundreds · 3C written 3 times: 3 × 100 = 300.
- LXXtens · 7L (50) plus XX (20) makes 70.
- IXones · 9I before X means 10 − 1 = 9. This saves writing VIIII.
300 + 70 + 9 = 379
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 CCCLXXVIIII (11 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CCCLXXIX (8 letters) is the standard.
