Material implication (rule of inference) - Wikipedia

The material conditional (also known as material implication) is an operation commonly used in logic. When the conditional symbol is interpreted as material implication, a formula is true unless is true and is false. Material implication can also be characterized inferentially by modus ponens, modus tollens, conditional proof, and classical reductio ad absurdum. WebIn intuitionistic logic, a proposition implies its double negation, but not conversely. This marks one important difference between classical and intuitionistic negation. Algebraically, classical negation is called an involution of period two. However, in intuitionistic logic, the weaker equivalence does hold. WebSuppose P → QQ → R are true. We want to prove that P → R is true. To do this suppose P is true. Because P → Q is true it follows that Q is true. Now because Q is true, from Q → R being true follows that R is true. We assumed P was true and we deduced that R is also true, therefore P → R as we wanted. introduction to investments pdf

In propositional logic, double negation is the theorem that states that "If a statement is true, then it is not the case that the statement is not true."
