The extended real number line is a concept in mathematics that extends the usual set of real numbers to include two additional elements: positive infinity (\\(+\\infty\\)) and negative infinity (\\(-\\infty\\)). This extension is useful because it allows for a more comprehensive way to handle limits, summations, integrals, and other mathematical constructs.
