notatsiooni

Notatsioon (the Estonian term for notation) is a system of symbols, signs, and conventions used to represent information, quantities, relationships, or processes. It enables concise communication and reasoning, allowing complex ideas to be expressed efficiently and shared across disciplines. Notatsioon evolves with practice, technology, and theoretical advances to improve clarity and utility.

In mathematics and science, notatsioon includes symbols for operations, constants, functions, and relations, such as +, −, ×, ÷, =, ≠, f(x), and set notation like { }. The standardization of notatsioon supports collaboration and education by reducing ambiguity. Historical variation in notatsioon gradually yielded to internationally accepted conventions, often through textbooks, publications, and peer review.

Notatsioon types vary by domain. Mathematical notatsioon encodes structure and rules; scientific notatsioon expresses very large or small numbers concisely, as in 3.0 × 10^8; musical notatsioon uses a staff and symbols to specify pitch and duration; programming notatsioon defines syntax and semantics of code; linguistic notatsioon may model grammar with symbolic rules.

Principles of good notatsioon include clarity, consistency, and economy. A well-designed notatsioon minimizes cognitive load, avoids superfluous symbols, and remains adaptable to new ideas. When conventions clash, communities may establish guidelines to preserve shared understanding while allowing domain-specific nuances.
