We don't need no stinkin' grammar
Hey, who cares if some Canadian math textbooks are riddled with grammatical errors and unsound items? After all, as Education Minister Jane Purves says, "The good news is that the mistakes do not involve the integrity of the mathematics." And one member of Newfoundland's Education Department called the critical report “nitpicking - What they’ve identified is that the majority of errors are differences in interpretation, opinion".
The article only gives one example of an error that does seem to involve mathematical reasoning. Still, it's sad to hear an Education Minister say that it's "good news" that a textbook is riddled with any kind of errors.
