How XCIII is built
Roman numerals are written one decimal place at a time, largest first.
- XCtens · 9X before C means 100 − 10 = 90. This saves writing LXXXX.
- IIIones · 3I written 3 times: 3 × 1 = 3.
90 + 3 = 93
The pair XC 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 LXXXXIII (8 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today XCIII (5 letters) is the standard.
