What is a proposition? A proposition is the basic building block of logic. It is defined as a declarative sentence that is either True or False, ...

Mathematics is really about proving general statements (like the Intermediate Value Theorem), and this too is done via an argument, usually called a proof. We ...

3. LOGIC AND PROOFS 3.1 Proofs with textual logic puzzles Logic in most discrete mathematics textbooks is fairly dry, although one text due out in Spring 2005 [Ensley and Crawley 2005] emphasizes puzzles and games as the context for many examples. Over the years we’ve experimented with using textual logic puzzles to try to motivate students.

Proofs in mathematics play a key role in its development and also guarantee the correctness of the results and theorems provided they are proved using logical reasoning. Given a set of hypotheses H 1 , H 2 ,…, H n , which can lead to a conclusion C , means H …

Proofs Discrete MathematicsAn Open Introduction 3.2Proofs ¶ Investigate! Decide which of the following are valid proofs of the following statement: If ab is an even number, then a or b is even. Suppose a and b are odd. That is, a = 2k + 1 and b = 2m + 1 for some integers k and m. Then ab = (2k + 1)(2m + 1) = 4km + 2k + 2m + 1 = 2(2km + k + m) + 1.
