This is a quick overview of the Implication (IMP) rule for Propositional logic. This rule states that from "if P then Q", you can derive "not-P or Q" and vice versa. The rule is a replacement or equivalence rule for some systems of logic (e.g. an Intelim system). In this video, I state the form of the rule, give a quasi-English example, provide a truth table showing that the two formulas are equivalent, and then go through a couple examples involving IMP.
Personally, I don't know how useful the rule is everyday argumentation. I don't think that I've ever heard someone reason "if P then Q" therefore "not-P or Q". So, if you have an example where someone does reason in this way, I'd love to hear it!
