How MMXLII is built
Roman numerals are written one decimal place at a time, largest first.
- MMthousands · 2MM is 2 × M (1,000), written out 2 times.
- XLtens · 4X before L means 50 − 10 = 40. This saves writing XXXX.
- IIones · 2I written 2 times: 2 × 1 = 2.
2,000 + 40 + 2 = 2,042
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 MMXXXXII (8 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today MMXLII (6 letters) is the standard.
- There's no letter for zero. The zero is simply left out, which is why 2042 has 3 parts, not 4.
2042 for a tattoo or engraving
- Shortened to two digits ('42), it's XLII. Many date tattoos use this shorter form.
- MMXLII has 6 letters. 100 of the 201 years from 1900 to 2100 are longer.
- 2042 will not be a leap year (365 days), and 1 January 2042 will be a Wednesday.
