Extended real number line - Wikipedia, the free encyclopedia
In mathematics, the affinely extended real number system is obtained from the real number system R by adding two elements: +∞ and −∞ (pronounced "positive infinity" and "negative infinity"). These...

The Real Number Line, Interval Notation and Set Notation ... The most intuitive way is to use the real number line. If we draw a line, designate a point on the line to be zero, and choose a scale, then every point on the line corresponds uniquely to a real number, and vice versa:

In the two previous sections, you have reviewed two of the three basic premises that underlie the concept of the real number line. First, we discussed sets and looked at some ways of describing sets. All of the sets of numbers that you worked with were subsets of the set of real numbers, which can be defined by:
