Monotonicity in Calculational Proofs David Gries Computer Science Cornell University May Abstract We discuss the use of weakening and strengthening steps in calcula tional proofs

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
