Indicate whether the deductive reasoning used is an example of affirming the hypothesis or denying the conclusion.
If a number is divisible by 3, then the sum of the digits of that number is divisible by 3.
The sum of the digits of a number is not divisible by 3. Therefore the number is not divisible by 3.

    The fallacy of affirming the hypothesis is based on the following hypothesis:conclusion set
    If A then B, IF B then A.
    The fallacy of denying the conclusion is
    If A, then B; If NOT B, then NOT A

    Does that help?

    If you are teaching Math, the way to teach these is to demonstrate with Venn Diagrams, in my opinion. STudents understand spacial arguments better than written logic.
