Inference Rule

An inference rule is a logical tool used to draw valid conclusions from given information. It helps us determine what new facts naturally follow from known facts, based on established logical principles. For example, if we know that "All humans are mortal" and "Socrates is human," an inference rule allows us to conclude that "Socrates is mortal." These rules ensure that reasoning is consistent and reliable, providing a structured way to expand our understanding from what we already know. They are fundamental in areas like mathematics, computer science, and philosophy to ensure conclusions are logically sound.
