What are the rules of implication?
Implication Rules: Implication Rules are prepositions that says that if A is present, then B also is present. It is denoted by A->B. As you can see we are not saying A causes B, but we are just saying that B occurs when A occurs. Also, that B is less likely to occur if A does not occur.
