Examples of Deductive Reasoning

In deductive reasoning we can say that the arguments can be valid or invalid but we can never say that the arguments are true or false. A deductive argument is an argument in which it is consideration that the premises provide a guarantee of the truth of the ending. In an argument, the conclusion is depending on the premises. The conclusion will be valid when the premises are true.
