Deductive reasoning is the process of logically deducing a conclusion from a set of statements known as premises. In such a deduction, one assumes the premises and deduces logically what would follow. [1] A rule of Deductive reasoning is that if the premises of a deductive argument are true, then the conclusion must be true, that is if the argument has a valid form.
