Knowledge is the basic foundation of what you know and have retained in your head. Answering a math equation correctly is knowledge because you have the skills to work out the problem and can give the direct answer. Answering most questions only relies on knowledge because we have been taught and trained to be able to state an answer. Intelligence is a persons ability to think, discover, create, and learn. Scientists who spend their lifetime working on and perfecting an experiment, formula, or invention use intelligence. They dont just think for a minute and state and answer, they have to ask deep and complicated questions. They ask themselves, colleagues, mentors. Their questions are useful and meaningful. Philosophers also use intelligence in asking questions about our world and our lives. Knowledge is a gift to have, but intelligence is what sets us apart
