When we say that x∈R does here x represents all real numbers at the same time or x represents only a single real number at one time.
How can a single variable(x) represent all the real numbers at the same time ?
when we write x∈R it means that x is an element of the set of real numbers, this means that x represents a single real number but then why we start to treat it as if x represents all the real numbers at once as in inequality suppose we have x>-2 this means that x can be any real number greater than -2 but then why we say that all the real numbers greater than -2 are the solutions of the inequality. x should represent a single real number right ? then how can x represents all the real numbers at the same time.Please help me...
