How DCCCVII is built
Roman numerals are written one decimal place at a time, largest first.
- DCCChundreds · 8D (500) plus CCC (300) makes 800.
- VIIones · 7V (5) plus II (2) makes 7.
800 + 7 = 807
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 807 has 2 parts, not 3.
