…The arguments we saw in the previous movie, were of the very simplest kind.…All A are B.…C is an A. Therefore, C is B.…In real life, you often need far more complex arguments to get to a conclusion.…In most cases, these arguments require a combination of…statements that relate to each other in different ways.…These different ways, are signified by logical operators.…The three basic operators of logic are AND, OR and NOT.…
They have more formal names.…AND is a conjuction. OR is a disjunction and NOT is a negation.…These simple operators allow us to make…complex statements about categories or groups of categories.…Let's say you have a selection of cupcakes and donuts on a table.…Some of them have red frosting,…some have yellow frosting.…You can use these operators to refer to the…cupcakes and donuts, just like you would in real life.…Cupcakes AND yellow, gives you a subsection of baked…goods that are both cupcakes and have yellow frosting.…
Donuts OR yellow gives you all the donuts plus all of the yellow cupcakes.…
