Geometry - Ch. 2: Proofs and Reasoning (2 of 46) Symbolic Notation
Visit http://ilectureonline.com for more math and science lectures! In this video I will show and give examples of the SYMBOLIC notations used in mathematical proofs: conditional (if p then q), converse (if q then p), inverse (if NOT p the NOT q), contrapositive (if NOT q then NOT p), and
From playlist GEOMETRY CH 2 PROOFS & REASONING
We begin our exploration into logic by analyzing LOGICAL STATEMENTS: 1) Define what a logical statement is 2) Recognize examples as logical statements or not logical statements 3) Use the symbols for "not", "and", and "or". 4) Break down a sentence into its logical structure. **********

Logic: The Structure of Reason
As a tool for characterizing rational thought, logic cuts across many philosophical disciplines and lies at the core of mathematics and computer science. Drawing on Aristotle’s Organon, Russell’s Principia Mathematica, and other central works, this program tracks the evolution of logic, be

Dana S Richards - Are You a Mathematician? - G4G14 April 2022
Martin Gardner is best known as a writer of recreational mathematics. It is often said he was not a mathematician; he said so himself. However he often contributed original results. These are found in math journals, his column and in the magic literature.
