Roman Numerals Chart
Tips of chart usage:
- Write numerals left to right, with the largest numeral first.
- The largest numeral possible is used at each stage.
- No more than three instances of same adjacent numeral. Occasionally number 4 is written not as IV but as IIII to add symmetry and balance to a watch or clock face.
- A smaller numeral such as I or X placed before a larger one has the effect of minus - thus IV is one less then five, or four. This is called the subtraction principle and only one numeral can be placed to the left. The small numeral must be a power of ten: I, X or C; (1, 10 or 100)
