When we talk about logical connectives, there are some common misunderstandings that can come up:
AND vs. OR: Many people think that “or” means one or the other, but in logic, when we say , it means at least one of them is true. It could even mean both are true!
IF...THEN: People often think this is a strong relationship. In logic, means if is true, then is also true. However, it doesn’t mean that causes to happen.
Negation: The NOT connective can be confusing. If we negate (), it just changes its truth value, but it doesn’t mean it’s the complete opposite. It’s just looking at it from a different angle.
