The real number line is a representation of all the real numbers on a horizontal line such that each point on the line corresponds to a real number and every real number corresponds to a point on the line.

The real number line allows us to visually display the numbers in which we are interested. A line is composed of infinitely many points. To each point we can associate a unique number, and with each number we can associate a particular point.

In advanced mathematics, the number line is usually called the real line or real number line, and is a geometric line isomorphic to the set of real numbers, with which it is often conflated; both the real numbers and the real line are commonly denoted R or ⁠ ⁠.

A real number line, or simply number line, allows us to visually display real numbers by associating them with unique points on a line. The real number associated with a point is called a coordinate .

The Real Number Line is like a geometric line. A point is chosen on the line to be the "origin" . Points to the right are positive, and points to the left are negative.

Here are the steps to represent a real number on a number line: Step 1: Draw a horizontal line with arrows on both ends and mark off the number 0 anywhere. The number 0 is called the origin. Step 2: Mark real numbers in equal length on both sides of …

The real number line is a horizontal line with arrows on both sides. It consists of the origin “0”. All the positive numbers are represented on the right side of the origin and all the negative numbers are represented on the left side of the origin, with a definite scale.
