The Amazing number 1089

1. Choose any 3-digit number which is not palindrome.

2. Reverse the digits of this number.

3. Find the difference of these 2 numbers.

4. Once again reverse the digits of the result.

5. Add the result (step 3) and the reversed result (step 4). You will get 1089.

e.g.    1. We have by arbitrarily selecting 123 (not palindrome)

          2. Reverse : 321

          3. Difference : 321 – 123 = 198

          4. Again reverse : 891

          5. Add : 198 + 891 = 1089

e.g.    1. Let us select 1 (i.e. 001, since it’s 3-digit) (not palindrome again)

          2. Reverse : 100

          3. Difference : 100 – 1 = 99 (i.e. 099)

          4. Again reverse : 990

          5. Add : 99 + 990 = 1089
