How DXC is built
Roman numerals are written one decimal place at a time, largest first.
- Dhundreds · 5D is 500.
- XCtens · 9X before C means 100 − 10 = 90. This saves writing LXXXX.
500 + 90 = 590
The pair XC 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 DLXXXX (6 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today DXC (3 letters) is the standard.
- There's no letter for zero. The zero is simply left out, which is why 590 has 2 parts, not 3.
About the number 590
- 590 is even and can be split into prime factors: 2 × 5 × 59, or in Roman numerals II × V × LIX.
- DXC has 3 letters. 907 of the numbers up to 1,000 have longer numerals.
