Boolean logic deals with truth values and how they combine. It treats statements as either true or false and uses operations like AND, OR, and NOT to form new truth values. Because everything it handles is restricted to two possibilities, it’s best described as an algebra where the variables can only be True or False. This tight two-valued system is what makes boolean logic foundational for computer logic and digital circuits, where decisions are based on binary outcomes. It isn’t geometry (the study of shapes), calculus (rates of change), or a method for storing data. The focus is on the manipulation and simplification of truth values, not on spatial, numerical, or storage concepts.
