How CXXX is built
Roman numerals are written one decimal place at a time, largest first.
- Chundreds · 1C is 100.
- XXXtens · 3X written 3 times: 3 × 10 = 30.
100 + 30 = 130
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 130 has 2 parts, not 3.
