Proof by Exhaustion (Maths): Definition, Examples & Methods

From the examples, you can see that we have added three virtual (or extra and temporary) rules of inference to our normal axiomatic logic. These are "hypothesis", "reiteration", and "deduction". The normal rules of inference (i.e. "modus ponens" and the various axioms) remain available. 1. Hypothesis is a step where one adds an additional premise to those already available. So, if your previous step S was deduced as: WebSep 5, 2024 · Deduction is the process by which we determine new truths from old. It is sometimes claimed that nothing truly new can come from deduction, the truth of a statement that is arrived at by deductive processes was lying (perhaps hidden somewhat) within the hypotheses.
