text: # Lix (readability test)
  
  LIX (abbreviation of Swedish läsbarhetsindex, "readibility index") is a readability measure indicating the difficulty of reading a text developed by Swedish scholar Carl-Hugo Björnsson. It is computed as follows:
  
  ${\text{LIX}}={\frac {A}{B}}+{\frac {C\cdot 100}{A}}$, where
  
  $A$ is the number of words,
  
  $B$ is the number of periods (defined by period, colon or capital first letter), and
  
  $C$ is the number of long words (more than 6 letters).
  
  Scores usually range from 20 ("very easy") to 60 ("very difficult").
