How DCCCXC is built
Roman numerals are written one decimal place at a time, largest first.
- DCCChundreds · 8D (500) plus CCC (300) makes 800.
- XCtens · 9X before C means 100 − 10 = 90. This saves writing LXXXX.
800 + 90 = 890
The pair XC 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 DCCCLXXXX (9 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today DCCCXC (6 letters) is the standard.
- There's no letter for zero. The zero is simply left out, which is why 890 has 2 parts, not 3.
