The Foundation of Logical Reasoning
💡 Think of it this way: Statements and propositions are like simple yes-or-no questions. They are like light switches: they can only be either ON (true) or OFF (false). There's no in-between.
📖 Definition: A statement is a sentence that can be viewed as either true or false. It is the basic unit of logical reasoning. Asked in Exam
🎯 Important: Truth and falsity are attributes of Propositions. Asked in Exam
TRUE
Statement is correct
FALSE
Statement is incorrect
"It's raining outside"
This statement can only be TRUE or FALSE.
• If you look outside and it's raining → Statement is TRUE
• If it's sunny outside → Statement is FALSE
Sentences Without Truth Values
Whether we call it a statement or a proposition, we're talking about the same thing—a sentence that makes a clear claim that you can check and say definitively if it's true or not.
💡 Key Insight: Non-statements are sentences that are like questions or commands—they can't really be true or false; they're just asking for information or telling someone to do something.
"Where is the nearest coffee shop?"
⚠️ No Truth Value
"Please close the window."
⚠️ No Truth Value
