How CCXXXVII is built
Roman numerals are written one decimal place at a time, largest first.
- CChundreds · 2C written 2 times: 2 × 100 = 200.
- XXXtens · 3X written 3 times: 3 × 10 = 30.
- VIIones · 7V (5) plus II (2) makes 7.
200 + 30 + 7 = 237
No subtraction is needed here: every letter is the same size or smaller than the one before it, so you simply add them up.
