The Real Number Line

A number line is a visual representation of the set of all real numbers. It consists of a horizontal line where every point corresponds to a unique real number. Zero (the origin) is in the center, negative numbers are to the left, and positive numbers are to the right.

Pro Tips

Infinity: The line extends forever in both directions (indicated by arrows).
Density: Between any two numbers on the line, there are infinitely many other numbers.
Absolute Value: The distance between a point and the origin is its absolute value.
