How do you use implies in logic?

If A and B represent statements, then A B means “A implies B” or “If A, then B.” The word “implies” is used in the strongest possible sense. As an example of logical implication, suppose the sentences A and B are assigned as follows: A = The sky is overcast. B = The sun is not visible.

What is equivalent to p implies q?

Thus, “p implies q” is equivalent to “q or not p”, which is typically written as “not p or q”. This is one of those things you might have to think about a bit for it to make sense, but even with that, the truth table shows that the two statements are equivalent.

The inverse of p → q is ¬p → ¬q. If p and q are propositions, the biconditional “p if and only if q,” denoted by p ↔ q, is true if both p and q have the same truth values and is false if p and q have opposite truth values.
