There are two ways to form logical arguments, as seen in the image below. ![]() In other words, an argument is valid when the conclusion logically follows from the truth values of all the premises. The rules of inference (also known as inference rules) are a logical form or guide consisting of premises (or hypotheses) and draws a conclusion.Ī valid argument is when the conclusion is true whenever all the beliefs are true, and an invalid argument is called a fallacy as noted by Monroe Community College. While the word “argument” may mean a disagreement between two or more people, in mathematical logic, an argument is a sequence or list of statements called premises or assumptions and returns a conclusion.Īn argument is only valid when the conclusion, which is the final statement of the opinion, follows the truth of the discussion’s preceding assertions.Ĭonsequently, it is our goal to determine the conclusion’s truth values based on the rules of inference. They’re especially important in logical arguments and proofs, let’s find out why! ![]() Jenn, Founder Calcworkshop ®, 15+ Years Experience (Licensed & Certified Teacher)
