Explanation:

In formation of greatest and smallest numbers we know the procedure of arranging the numbers in ascending and descending order. We have learnt already that the greatest number is formed by arranging the given digits in descending order and the smallest number by arranging them in ascending order. The position of the digit at the extreme left of a number increases its place value. So the greatest digit should be placed at the extreme left side of the number to enhance its value.

If one of the given digit is 0, we never write the digit 0 at the extreme left place, instead we write 0 at the second place from the left to get the smallest number.
