Webb3. The rule of inference that says we can conclude A, given A ∧ B, is called "simplification". This is potentially confusing, because in algebra, we often use the word "simplification" to refer to moves that are equivalences ( ⇔ ), whereas this rule only goes one way ( ( A ∧ B) A ). In this case, our statement A is ¬ p, and we can obtain ... WebbRULE OF INFERENCE: CONJUNCTION. For example, the rules of simplification and conjunction emerge directly from the fact that when two sentences are connected by a conjunction, what’s being asserted is that both conjuncts are true. Thus if a conjunction is true, we can derive either conjunct. WebbSimplification (Simp.)-P and Q-Therefore P. Absorption (Abs.)-If P then Q-Therefore If P (P or Q) Addition (Add.)-P-Therefore P or Q.
