How CXVII is built
Roman numerals are written one decimal place at a time, largest first.
- Chundreds · 1C is 100.
- Xtens · 1X is 10.
- VIIones · 7V (5) plus II (2) makes 7.
100 + 10 + 7 = 117
No subtraction is needed here: every letter is the same size or smaller than the one before it, so you simply add them up.
