Interpretation: The so-called deductive reasoning is the process of drawing specific statements or individual conclusions from the general premise through deduction. The most typical and important application of deductive reasoning usually exists in logic and mathematical proof.

Example:

1. A word can be positive, negative or neutral. "Result" is a neutral word, so "Result" is neither a commendatory nor a derogatory term.

2. In breeding, seeds can germinate only when they reach a certain temperature. The breeding did not reach a certain temperature, so the seeds did not germinate.

3. If a figure is a square, then its four sides are equal; The four sides of this figure are not equal, so it is not a square.

Deductive reasoning method:

1, three-stage deduction method: based on two property judgments related to a concept, another property judgment is derived and a conclusion is drawn.

2. Joint decomposition method: A thinking reasoning method in the form of joint reasoning is derived from the truth value of joint judgment.

3. Chain deduction method: In a proof process or a complicated reasoning process, the conclusion of the previous reasoning is taken as the premise of the latter reasoning, and it is deduced step by step until the required conclusion is deduced.

4. Comprehensive induction: an inference method that summarizes a general conclusion on the premise of a large number of individual knowledge.
