If an argument happens to be invalid, of course, it … Webcomplete system for constructing formal proofs of validity. A complete system must allow us to be able to make a formal proof for any valid argument that can be translated into propositional logic form, the level of argumentation consisting of simple statements and the five logical connectives.

WebGiven the claim: "if n + 1 is odd, then n is even." State if this proof is Valid, Invalid, or Neither (the validity or invalidity cannot be determined) proof of the claim. Proof Suppose by contradiction n + 1 is even. Then, n+1 = 2k for some integer k, so that n = 2k - 1 = 2(k - 1) + 1. Therefore, n is odd, a contradiction to the idea n is even.
