**Propositional logic**is a branch of mathematics that formalizes logic. It is based on simple sentences known as propositions that can either be true or false. Propositional logic includes rules of inference, replacement and generalization that allow for formal proofs of logic. It is also one of the fundamental building blocks of artificial intelligence.

## Propositions

A proposition is a particular kind of sentence that can either be true or false. For example:Premise 1: If it's sunny then it's not raining.

Premise 2: It's sunny.

Conclusion: It's not raining.

In the example above, both the premises and the conclusion are propositions.Premise 2: It's sunny.

Conclusion: It's not raining.
