In uncomplicated introductions to mathematical research, the therapy of the logical and algebraic foundations of the topic is inevitably really skeletal. This ebook makes an attempt to flesh out the bones of such remedy via offering an off-the-cuff yet systematic account of the rules of mathematical research written at an easy point.
