How do you know if your proposition or not?
This kind of sentences are called propositions . If a proposition is true, then we say it has a truth value of “true”; if a proposition is false, its truth value is “false”. 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 the function of a proposition?
