Formation of Numbers
Two different numbers can be formed using 2 different digits. In a 2-digit number 42. The digits are 4 and 2. We can form another number 24 by using same digits.
The greater number is formed by arranging the given digits in descending order.
|
42 |
is greater than |
24 |
The smaller number is formed by arranging the given digits in ascending order.
|
24 |
is smaller than |
42 |
We form the greater number by repeating the greater digit. 4 is the greater digit in the number.
|
42 |
→ |
44 |
44 is the greater number formed.
We form the smallest number by repeating the smallest digit.
|
42 |
→ |
22 |
Note: We cannot form any number by writing zero on the extreme left.
