## How are conjunctions and disjunctions alike?

Conjunctions and disjunctions are ways of joining logical statements, with every joined, compound statement either true or false. For conjunctions, both statements must be true for the compound statement to be true. For disjunctions, only one statement needs to be true for the compound statement to be true.

## What is the difference between conjunction and conditional?

Conjunctions mean that you have both or you have neither of them. Disjunction (Or Statements) Disjunction is symbolized by V and read “or”. A conditional statement consists of two parts: the part that is in front of the arrow is the antecedent and the part that follows the arrow is the consequent.

Why are P and Q used in logic?

The propositions are equal or logically equivalent if they always have the same truth value. That is, p and q are logically equivalent if p is true whenever q is true, and vice versa, and if p is false whenever q is false, and vice versa. If p and q are logically equivalent, we write p = q.

## What is disjunct and examples?

In linguistics, a disjunct is a type of adverbial adjunct that expresses information that is not considered essential to the sentence it appears in, but which is considered to be the speaker’s or writer’s attitude towards, or descriptive statement of, the propositional content of the sentence, “expressing, for example.
