Cách sử dụng
The tilde is a symbol that looks like a wavy line (~) and is usually found on computer keyboards. It is used in various ways, such as to indicate approximation, as in “~10 minutes” (which means about 10 minutes), or to denote a range of numbers, as in “3~5” (which means from 3 to 5). It can also be used in Spanish or Portuguese to indicate a certain type of pronunciation, such as ñ or ã.
