How DLIX is built
Roman numerals are written one decimal place at a time, largest first.
- Dhundreds · 5D is 500.
- Ltens · 5L is 50.
- IXones · 9I before X means 10 − 1 = 9. This saves writing VIIII.
500 + 50 + 9 = 559
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 DLVIIII (7 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today DLIX (4 letters) is the standard.
