How DL is built
Roman numerals are written one decimal place at a time, largest first.
- Dhundreds · 5D is 500.
- Ltens · 5L is 50.
500 + 50 = 550
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 550 has 2 parts, not 3.
