How DCCIV is built
Roman numerals are written one decimal place at a time, largest first.
- DCChundreds · 7D (500) plus CC (200) makes 700.
- IVones · 4I before V means 5 − 1 = 4. This saves writing IIII.
700 + 4 = 704
The pair IV uses subtraction: a smaller letter before a larger one is taken away from it. Only six pairs work this way: IV, IX, XL, XC, CD and CM. More on subtraction
Mistakes to avoid
- Not DCCIIII (7 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today DCCIV (5 letters) is the standard.
- There's no letter for zero. The zero is simply left out, which is why 704 has 2 parts, not 3.
About the number 704
