What does exist mean in math?

Answer 1

In mathematics, "exist" refers to the existence of a mathematical object or solution that satisfies certain conditions or properties within a given context. For example, when we say "there exists an x such that f(x) = 0," we mean that there is at least one value of x for which the function f evaluates to zero. The concept of existence is often formalized using quantifiers, such as the existential quantifier (∃), which denotes "there exists."
