Define deductive reasoning, and introduce the laws of logic (Law of Detachment: If p→q is a true conditional and p is true, then q is true. Law of Syllogism: If p→q is a true conditional, and q→r is a true conditional, then p→r is a true conditional).
Provide several examples using the law of detachment and the law of syllogism.
Provide some examples that demonstrate how to make arguments using deductive reasoning.
Provide examples of converse, inverse and contrapositive of "if-then" statements.
This packet should help a learner seeking to understand deductive reasoning.
