Explain how to order a set of real numbers ?

Ordering the real numbers is a process of arranging them in a particular order either from smallest number to the largest number or largest to the smallest. For example a set of real numbers is given to be {25,6,115,27,15,18} Then, this set in not in a regular pattern, so we arrange in in an increasing order as {6,15, 18, 25, 27, 115}
