How CDLX 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.
400 + 60 = 460
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 LDX. It looks like a shortcut, but L is never written before a larger letter to subtract. The correct form is CDLX.
- Not CCCCLX (6 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CDLX (4 letters) is the standard.
- There's no letter for zero. The zero is simply left out, which is why 460 has 2 parts, not 3.
About the number 460
