J Hildebrand Evenodd proofs Practice problems Solutions The problems below illustrate the various proof techniques direct proof proof by contraposition proof by cases and proof by contradiction see the separate handout on proof techniques 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.
