NOTE: the order in which rule lines are cited is important for multi-line rules. For example, in an application of conditional elimination with citation "j,k →E", line j must be the conditional, and line k must be its antecedent, even if line k actually precedes line j in the proof. The only multi-line rules which are set up so that order doesn't matter are &I and ⊥I.

This is clearly a formal version of the method of proof by cases. Each of the Pi represents one of the cases. Each subproof represents a demonstration that, in each case,
