Ordering real numbers means arranging them in increasing or decreasing order, from smallest to largest or largest to smallest. The real number line is a visual representation of real numbers, which helps to visualize the order of real numbers. The symbols used for ordering real numbers are: '<' (less than), '>' (greater than), '≤' (less than or equal to) and '≥' (greater than or equal to).

Real numbers are used to measure temperature, since it is impossible to accurately measure an infinite number of points on a thermometer. The order of real numbers can be used to determine the difference between two points on a number line. The distance between two points is measured by the absolute value of the real numbers. Real numbers are used in various computer programming languages to create a program that can accurately calculate the distance between two points on a number line.
