How to say "notation" in Japanese

• 表記ひょうきCommon
  noun, suru verb, transitive verbThe broadest and most common choice: the act or manner of expressing something in writing, or the written form itself. Covers how words, numbers or names are written down, not necessarily a formal system.

  What is difficult about Japanese is how characters are used in its writing system.
• 記法きほう
  nounA notation in the sense of a set of conventions or a method for writing something, especially in technical fields such as mathematics or programming. Less common, and more specialized than 表記.
• 表記法ひょうきほう
  nounNotation as a method or system of written representation; also covers orthography and writing systems. Suits formal or technical discussion of how something is systematically written, but is less common than 表記.

• 表記体系ひょうきたいけい
  nounNotation understood as a whole system of notation, emphasizing the structured, systematic aspect. A narrower, more formal term; use it when you specifically mean a system rather than notation in general.
• ノーテーション
  nounA katakana loanword meaning notation, typically in technical or academic contexts such as mathematics. Less common than the native options, and seldom the word you want in everyday writing.

Use 表記 for written representation in general, 記法 or 表記法 for a system or method of notation (e.g. in mathematics or music), 表記体系 for an entire notation system, and 「ノーテーション」 as a rare loanword alternative.
