I'm glad I watched that video, I know some really useful rules now that I need to remember when working with Roman numerals:
  • When a symbol appears after a larger symbol, it is added (eg: VI = V + I = 5 + 1 = 6)
  • When a symbol appears before a larger symbol it is subtracted (eg: IX = X – I = 10 – 1 = 9).
  • The numerals are written like this because you can not have more than three matching symbols in a row.

 

The following rhyme may help to remember these rules.  

 

When “left” is small and “right” is bigger,
Subtract the “left” from “right-hand” figure.
