Truth tables – negation, conjunction, disjunction (“not”, “and”, “or”) Truth tables are a way of analyzing how the validity of statements (called propositions) behave when you use a logical “or”, or a logical “and” to combine them.
Disjunction. In logic, a disjunction is a compound sentence formed by using the word or to join two simple sentences. The symbol for this is ν. (whenever you see ν read 'or') When two simple sentences, p and q, are joined in a disjunction statement, the disjunction is expressed symbolically as p ν q.
The items on either side of the disjunctive conjunction are called disjuncts. Examples and Observations: "The statement p or q is a disjunction. It is true when p is true, or when q is true, or when p and q are both true; it is false when both p and q are false. For example:Either Mac did it or Bud did it.
Watch this video lesson to learn how to identify conjunctions and disjunctions. Also learn the connectors that are used with each. Learn how you can use them to make statements. 2014-01-03
Conjunction is a truth-functional connective similar to "and" in English and is represented in symbolic logic with the dot " ". Ordinary language definition of the dot: a connective forming compound propositions which are true only in the case when both of the propositions joined by it are true.

Conjunctions In Math. Joining two statements with "and" is a conjunction, which means both statements must be true for the whole compound statement to be true. Conjunctions are symbolized with the ∧ character, so these two discrete statements can be combined in a compound statement: Statement p: Squares are rectangles
The statement p q is a conjunction. Definition: A conjunction is a compound statement formed by joining two statements with the connector AND. The conjunction "p and q" is symbolized by p q. A conjunction is true when both of its combined parts are true; otherwise it is false. Now that we have defined a conjunction, we can apply it to Example 1.
Unit 2 - Compound Statements & Connectives and Truth Tables for Negation, Conjuction, & Disjunction ... Conjunction, and Disjunction ... In the previous two examples, the components of the conjunction and disjunction were known to be true or false. For example, we know that "the sun is hot" is always a true statement.
With a conjunction, both statements must be true for the conjunction to be true; but with a disjunction, both statements must be false for the disjunction to be false. One way to remember this is with the following mnemonic: 'And’ points up to the sand on top of the beach, while ‘or’ points down to the ore deep in the ground.
