What 8 concepts are covered in the Truth Tables Calculator?
- conjunction
- a word used to connect clauses or sentences or to coordinate words in the same clause
- disjunction

- the state or property of being equivalent.
- modus ponens
- If conditional statement if p then q
p --> q - modus tollens
- If conditional statement if not p then not q
!p --> !q - negation
- reverses the truth value of a given statement.
~ - proposition
- a declarative sentence that is either true or false (but not both)
- truth table
