Find out the meaning of deductive reasoning: meaning, examples.
What is it?
Deductive reasoning is a reasoning
that starts from given & known statements
to get a specific conclusion,
usually by using logic.
Starting from p → q and q → r,
you get p → r logically.
So using the law of syllogism is deductive reasoning.
Law of contrapositive and law of detachment
are also deductive reasoning you've learned before.
Starting from x + 2 = 3,
you write -2 on both sides: x + 2 - 2 = 3 - 2
(This is the logic part: reflexive property.)
then you get the conclusion: x = 1.
So solving equations is deductive reasoning.
