How DCI is built
Roman numerals are written one decimal place at a time, largest first.
- DChundreds · 6D (500) plus C (100) makes 600.
- Iones · 1I is 1.
600 + 1 = 601
No subtraction is needed here: every letter is the same size or smaller than the one before it, so you simply add them up.
Mistakes to avoid
- There's no letter for zero. The zero is simply left out, which is why 601 has 2 parts, not 3.
