Why you use hyphens in math?

Hyphens in math are typically used to indicate a range of values or to clarify the relationship between numbers, such as in "3-5" to denote all integers between 3 and 5, inclusive. They help avoid ambiguity and improve readability, particularly in expressions involving negative numbers or complex equations. Additionally, hyphens can be used in composite numbers or terms to connect related concepts, like "two-dimensional" or "well-defined."
