Notes:
A conjunction is a compound statement that is made by combining two or more statements with the word "and". If any of the statements is false, then the entire conjunction is false. If all statements are true, then the conjunction is true. We can replace the word "and" with the symbol ˄.
A disjunction is a compound statement that is made by combining two or more statements with the word "or". If any of the statements is true, then the entire disjunction is true. If all statements are false, then the disjunction is false. We can replace the word "or" with the symbol ˅.
