How CXLVI is built
Roman numerals are written one decimal place at a time, largest first.
- Chundreds · 1C is 100.
- XLtens · 4X before L means 50 − 10 = 40. This saves writing XXXX.
- VIones · 6V (5) plus I (1) makes 6.
100 + 40 + 6 = 146
The pair XL 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 CVLI. It looks like a shortcut, but V is never written before a larger letter to subtract. The correct form is CXLVI.
- Not CXXXXVI (7 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CXLVI (5 letters) is the standard.
