Proposition

A proposition is a simple statement used in mathematics and logic theory to make a statement that has a truth value of true or false, but not both. Let's look at some examples. "The sky is blue" is an example of a propositional statement that has the truth value of true. The statement "5 plus 2 is equal to 8" is a proposition that is false. Sentences that cannot be evaluated for their truthfulness are not propositions. For example, "What time is lunch?" is a question, not a proposition. The statement "P is less than 5" is not a proposition because it depends on the value of the variable P. Since this value is unknown, the statement cannot be evaluated true or false, and therefore is not a proposition. Let's try some examples and you decide. "Lions are bigger than cats." Is this a statement? Is this a proposition? If so, what is the truth value of this proposition? Think a
