+ This paragraph has 423 characters. We know that
+ because we counted it. It is very simple to count, because
+ the Emacs editor we are using has a function ``advance
+ by one character.'' And with the prefix command (that's
+ Emacs terminology) you can execute ``advance by
+ one character'' 423~times. Now, let's hope that this text
+ is representative of ordinary text so that our average
+ number of characters per pica is correct.
