Deductive Reasoning

Deductive Reasoning (some times called top-down logic) is a type of formal reasoning that goes from general truths to specific things. A conclusion is based on the concordance of multiple premises assumed to be true. If the premises, are true and conclusion is certainly true as a result, argument is valid. This reasoning is also capable of being confirmed. Its most common form is syllogism.

Determining Deductive Reasoning

If 1= 2 premise
& 2= 3 premise
then 1=3 premise

*If premises are assumed to be true and the conclusion is certainly true as a result, conclusion is then valid.
*If premises are actually true and conclusion is valid, conclusion is then sound.
