Question

Okay so I need some help (go figure)... I need some help understanding logical equivalence. How can I tell if a statement is or is not logically equivalent to another?

Answer 1

tatement (Conditional): If I find Dr. Madness’s layer, then Dr. Madness will be defeated
This is the statement that I am using for my assignment and these are the inverse, converse and contrapostive:
1. Code #1 (Inverse): If I do not find Dr.Madness’s layer, then Dr. Madness will not be defeated
2. Code #2 (Converse): If Dr. Madness is defeated, then I found his layer.
3. Code #3 (Contrapositive): If Dr. Madness is not defeated, then I did not find his layer
