How CCCXCVI is built
Roman numerals are written one decimal place at a time, largest first.
- CCChundreds · 3C written 3 times: 3 × 100 = 300.
- XCtens · 9X before C means 100 − 10 = 90. This saves writing LXXXX.
- VIones · 6V (5) plus I (1) makes 6.
300 + 90 + 6 = 396
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 CCCLXXXXVI (10 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CCCXCVI (7 letters) is the standard.
