Ordering of Number.

To order number means to arrange a given set of figures from the smallest to the biggest based on the magnitudes, sizes or values of those given sets of numbers.

There are several methods for ordering numbers, each of which has advantages and disadvantages depending on the situation. One popular method is to use the natural order of numbers, which means arranging numbers from smallest to largest based on their value. This is often done using a simple numerical sorting algorithm that compares pairs of numbers in turn and places them in ascending or descending order.

Examples :

Arrange the following sets of figures in ascending order of magnitude.

A. 56376, 45876. 98453, 12765, 23675
