Mathematically, logical operators combine propositions to make other propositions by following some specific rules. Propositional logic is used in artificial intelligence for planning, problem-solving, intelligent control and most importantly for decision-making.
Why do we need to learn about proposition?
The concept of propositions is relevant because it allows us to state or restate claims in an argument to make the argument clearer or to structure the argument so it can be put into logical form as long as the statement we make captures the same exact meaning or propositional content.

For example, “Grass is green”, and “2 + 5 = 5” are propositions. The first proposition has the truth value of “true” and the second “false”.
What is proposition explain different logical connectives used in proposition with the help of example?

| Conjunction | And | ∧ |
| Disjunction | Or | ∨ |
| Conditional | If-then | → |
| Biconditional | If and only if | ↔ |
What is the difference between statement and proposition?
The difference is that statements merely express propositions. So a statement is “true” in virtue of the proposition it expresses being true. That is why only propositions are truth-bearers, while things like statements, thoughts, or ideas are not.
