How CDLXVIII 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.
- LXtens · 6L (50) plus X (10) makes 60.
- VIIIones · 8V (5) plus III (3) makes 8.
400 + 60 + 8 = 468
The pair CD 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 CCCCLXVIII (10 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CDLXVIII (8 letters) is the standard.
