OK, this time I'm really stymied.   It appears that Maple doesn't follow the same rules of operator precedence when it comes to logical operators.  p &and q &or r should be the same as r &or p &and q, but it isn't.  What gives, and how can I remedy it?

So, how come in command line, if I enter a/(b*c), I am returned with a/b/c?  Is there anyway to preserve 'intelligent' denominator groupings?
