Whether this is a bug depends on what the code is meant to do. If it's
supposed to give you the answer for 1+(5*8)+1, then it's fine (though
I'd call it bad code because there's a significant potential for
confusion). If you wanted to know what 6*9 was, then you have a
problem...
Just need to know what the QUESTION is.

Um, what?
