# Ordering

The numbers in ascending and descending order.

Ordering

Consider the numbers 2 and 7. By using these numbers we shall form the greatest and smallest two digit numbers. The two−digit numbers formed using 2 and 7 are 27,72,22,77. (77 is the greatest and 22 is the smallest 2 digit numbers) Similarly, 7, 4 and 8 are given numbers. By using these numbers shall we form the greatest and smallest three digit number.

444, 478, 487, 748, 777, 784, 847, 874 888, and so on

Arrange the given digits from the smallest number to greatest number, we get Ascending order.

478, 487, 748, 784, 847, 874 and so on

Arrange the above from the greatest number to smallest number, we get Descending order.

874, 847, 784, 748, 487,478

888 is the greatest number and 444 is the smallest number.
