A notation system is a structured method of representing information, often using symbols, signs, or characters. It helps convey complex ideas in a simplified manner, making it easier to understand and communicate. Common examples include mathematical notation, musical notation, and programming languages, each designed for specific fields. These systems provide a universal language that allows individuals to share knowledge efficiently. For instance, mathematical notation uses symbols like "+" and "=" to express calculations, while musical notation employs notes and rests to indicate rhythm and pitch. Overall, notation systems enhance clarity and precision in various disciplines.
