PPT-More Proofs

review The Rule of Assumption A Assumption is the easiest rule to learn It says at any stage in the derivation we may write down any WFF we want to That WFF only depends on itself ampElimination ampE. We present a metatheorem concerning monotonicity of posi tions in a formula that should have a more prominent place in the teaching of such proofs and give supporting examples Introduction In making a calculational step like eakening we are implici Logic and Proof.
