In this post, I am going to prove Kaprekar's Constant. Now let us prove this by taking some examples . 3-Digit Number Rule: Example 1: I'm taking a three-digit number '658'. You can assume any 3-digit number. Condition : You should not assume the same numbers as 999,111,222, etc. Because if you take in the form a Descending number - Ascending number, you will get 111-111=000 . But you can assume 3-digit numbers like this: 665, 991,344 . For this number, the Descending number is '865' and the Ascending number is '568'. Subtract the Ascending number from Descending number . Next, take the number 297. For this number, the Descending number is '972' and the Ascending number is '279'. Subtract the Ascending number from Descending number . Next, take the number 693. For this number, the Descending number is '963' and the Ascending number is '369'. Subtract the Ascending number from Descending number. Next, take the number 594....
