system of symbols for writing
A system of signs and marks that people agree to use to write numbers, music, or other special information.
用法模式：
use [type] notation to represent [something]
常见错误：
Learners sometimes confuse 'notation' with 'note'. 'Notation' is the whole system of symbols (for example, musical notation), while 'note' is usually one small piece of information, like a short message or a single musical sound. Learners may also say 'math symbols' when a teacher expects the more formal term 'mathematical notation'.

brief written mark or comment
A short written mark or comment that you add to something written or drawn to give more information.
用法模式：
add a notation to [a document / a file / the margin]
常见错误：
Learners often use 'notation' when 'note' or 'comment' is more natural, especially in everyday speech (e.g. saying *"I left a notation on the fridge"* instead of *"I left a note on the fridge"*). 'Notation' in this sense is usually used in more formal, written contexts such as documents, files, and academic texts.
近义词
annotation (Very close in meaning; often used for more detailed or scholarly comments on a text.)
|
note (More general and common; can be spoken or written, while 'notation' is more formal and document-focused.)
反义词
omission (If you omit information, you leave it out instead of adding a written notation.)
