What is a notational system primarily used for?

The notational system is primarily used for representing different quantities or characters. This encompasses a variety of systems, such as numerical notation for counting and calculations, algebraic notation for expressing mathematical relationships, and even programming languages that represent commands and data structures. Notational systems serve as a way to communicate complex ideas succinctly through symbols, letters, numbers, or a combination of these elements that can express a wide array of information.

While calculating mathematical equations, storing digital data, and connecting multiple systems are important aspects of information technology, they are more operational or functional applications rather than the primary purpose of a notational system itself. A notational system's core function lies in the representation and expression of information to convey meaning, making it essential for effective communication and understanding across multiple domains.
