Your particular example, writing the set of real numbers using set-builder notation, is causing some grief because when you define something, you're essentially creating it out of thin air, possibly with the help of different things.

The set $$\{ 1,2,3,4,5, \cdots \} $$ of all natural numbers is denoted by the symbol $$\mathbb{N}$$.There is no difference. The notation $(-\infty, \infty)$ in calculus is used because it is convenient to write intervals like this in case not all real numbers are required, which is quite often the case. eg. $(-1,1)$ only the real numbers between -1 and 1 (excluding -1 and 1 themselves).A symbol for the set of real numbers In mathematics, a real number is a number that can be used to measure a continuous one- dimensional quantity such as a distance, duration or temperature.
