First of all, these rules will dazzle and astound you (and numerous other admirers) with the ease they provide you in working logic proofs. For example, just try proving the validity of the following argument by using only implication rules:
Alas, you can’t. But, luckily for you, when you apply the equivalence rules I explain in this chapter, problems like these are just momentary distractions on an otherwise cloudless day. Even more good news: Equivalence rules are generally easier and more flexible to use within proofs for several important reasons, which I also explain.
