How DCCLXX is built
Roman numerals are written one decimal place at a time, largest first.
- DCChundreds · 7D (500) plus CC (200) makes 700.
- LXXtens · 7L (50) plus XX (20) makes 70.
700 + 70 = 770
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 770 has 2 parts, not 3.
