4) Come to class with questions about the proof of theorem 3.4 starting on page 86. 5) Do exercise #7 (both parts) in section 3.1 6) Use proof by contradiction to prove that any integer n cannot be both even and odd. We proved this result before using direct proof in conjunction with the division algorithm.

Nov 20, 2013 · Logic and Truth Tables. We can represent the truth of expressions in a tabular form called “truth tables.” These tables consider all cases and can add great insight into otherwise complicated expressions. Here are examples of some of most basic truth tables. The truth table for negation (“not”)

SYMBOLIC LOGIC. INTRODUCTION TO INDIRECT PROOF. Indirect proof is based on the classical notion that any given sentence, such as the conclusion, must be either true or false. We do indirect proof by assuming the premises to be true and the conclusion to be false and deriving a contradiction. Getting a contradiction shows us that it is

Such approaches lead students to believe that proof is an exercise in logic that validates unimportant statements (Herbst, 2002), or that proof is a forced school task to verify something the students are already convinced of based on examples (de Villiers, 1995).

In the two examples which follow I describe how I've come to present two particular topics, validity and basic notions of proof and counterexample. Example: Teaching about Validity My main purpose in teaching about validity is to lay the groundwork for understanding the process of deductive reasoning.

WLOG – ‘Without loss of generality’ is a simplifying assumption which is used in proof. In a proof you may have to cover a number of choices which involves the same proof for each selection.
