Theorems in propositional logic | Rules of inference
In propositional logic, disjunction elimination (sometimes named proof by cases, case analysis, or or elimination), is the valid argument form and rule of inference that allows one to eliminate a disjunctive statement from a logical proof. It is the inference that if a statement implies a statement and a statement also implies , then if either or is true, then has to be true. The reasoning is simple: since at least one of the statements P and R is true, and since either of them would be sufficient to entail Q, Q is certainly true. An example in English: If I'm inside, I have my wallet on me.If I'm outside, I have my wallet on me.It is true that either I'm inside or I'm outside.Therefore, I have my wallet on me. It is the rule can be stated as: where the rule is that whenever instances of "", and "" and "" appear on lines of a proof, "" can be placed on a subsequent line. (Wikipedia).
