How CCLXIII is built
Roman numerals are written one decimal place at a time, largest first.
- CChundreds · 2C written 2 times: 2 × 100 = 200.
- LXtens · 6L (50) plus X (10) makes 60.
- IIIones · 3I written 3 times: 3 × 1 = 3.
200 + 60 + 3 = 263
No subtraction is needed here: every letter is the same size or smaller than the one before it, so you simply add them up.
