Uses Deductive Reasoning is a process of reasoning in which one draws conclusions from a set of given facts. It involves making an inference, or logical conclusion, based on the information that is known. This type of reasoning is often used in mathematics and science, as well as in everyday life. In deductive reasoning, the conclusion must necessarily follow from the premises; if the premises are true, then the conclusion must also be true. This type of reasoning is contrasted with inductive reasoning, which involves making generalizations based on observations.
