How CMXLIV is built
Roman numerals are written one decimal place at a time, largest first.
- CMhundreds · 9C before M means 1,000 − 100 = 900. This saves writing DCCCC.
- XLtens · 4X before L means 50 − 10 = 40. This saves writing XXXX.
- IVones · 4I before V means 5 − 1 = 4. This saves writing IIII.
900 + 40 + 4 = 944
The pairs CM and XL 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 DCCCCXXXXIIII (13 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today CMXLIV (6 letters) is the standard.
