About Logic Proof Solver . For example, (a -> b) & a becomes true if and only if both a and b are assigned true. Like most proofs, logic proofs usually begin with premises --- statements that you're allowed to assume. The conclusion is the statement that you need to prove. The idea is to operate on the premises using rules of inference until you arrive at the conclusion. Rule of Premises. You may write down a premise at any point in a proof.
