How CCLXX is built
Roman numerals are written one decimal place at a time, largest first.
- CChundreds · 2C written 2 times: 2 × 100 = 200.
- LXXtens · 7L (50) plus XX (20) makes 70.
200 + 70 = 270
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 270 has 2 parts, not 3.
