Query: Ugh!

We are using this book for my Ph.D.-level microeconomics class, which happens to be taught by one of the authors of the book. I have been struggling with the text for two months now, and find it more and more frustrating at every turn. I think this book spends far too much time turning simple economic concepts into arcane mathematical formulae without nearly enough attention to drawing out the important economic issues behind the math. I've had econ classes before. I know there are issues out there, and that economics is not just math, but you would never know it from this book!
