How MCMXLV is built
Roman numerals are written one decimal place at a time, largest first.
- Mthousands · 1M is 1,000.
- 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.
- Vones · 5V is 5.
1,000 + 900 + 40 + 5 = 1,945
The pairs CM and XL 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 MDCCCCXXXXV (11 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today MCMXLV (6 letters) is the standard.
1945 for a tattoo or engraving
- Shortened to two digits ('45), it's XLV. Many date tattoos use this shorter form.
- MCMXLV has 6 letters. 100 of the 201 years from 1900 to 2100 are longer.
- 1945 was not a leap year (365 days), and 1 January 1945 was a Monday.
