Statement in Logic
The word Logic is derived from the Greek word ‘Logos’ which means reason. Logic deals with the methods of reasoning. Logic is a process by which we arrive at a conclusion from known statements or assertions with the help of valid assumptions. The valid assumptions are known as laws of logic. The Greek philosopher and […]
