How CDXCIV is built
Roman numerals are written one decimal place at a time, largest first.
- CDhundreds · 4C before D means 500 − 100 = 400. This saves writing CCCC.
- XCtens · 9X before C means 100 − 10 = 90. This saves writing LXXXX.
- IVones · 4I before V means 5 − 1 = 4. This saves writing IIII.
400 + 90 + 4 = 494
The pairs CD and XC and IV use 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 CCCCLXXXXIIII (13 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CDXCIV (6 letters) is the standard.
