What is argument in discrete structure?

An argument form, or argument for short, is a sequence of statements. All statements but the last one are called premises or hypotheses. An argument is valid if the conclusion is true whenever all the premises are true.

What is argument in mathematical logic?

In mathematics, an argument can be formalized using symbolic logic. In that case, an argument is seen as an ordered list of statements, each one of which is either one of the premises or derivable from the combination of some subset of the preceding statements and one or more axioms using rules of inference.

What is an argument in reasoning?

In logic and philosophy, an argument is a series of statements (in a natural language), called the premises or premisses (both spellings are acceptable), intended to determine the degree of truth of another statement, the conclusion.

What is the validity of an argument?

In effect, an argument is valid if the truth of the premises logically guarantees the truth of the conclusion. The following argument is valid, because it is impossible for the premises to be true and the conclusion nevertheless to be false: Elizabeth owns either a Honda or a Saturn.

What is a good argument?

A good argument is one in which the premises give good reasons to believe the conclusion is true. A good argument is one that presents a conclusion and then gives good reasons for accepting it. A bad argument is one in which the premises do not give good reason to accept the conclusion.

What is a true argument?

TRUE: If an argument is sound, then it is valid and has all true premises. Since it is valid, the argument is such that if all the premises are true, then the conclusion must be true. A sound argument really does have all true premises so it does actually follow that its conclusion must be true. 3.
