MAGICAL NUMBER- KAPREKAR'S CONSTANT

This one is the best mathematics trick. Try this out......

1) Think of any four digit number that has at least two different digits(for example.1234 is allowed,2222 is not as no second digit).

2) Now arrange the digits in descending order and then in ascending order giving you two different numbers.

3) Subtract the smaller number from the larger one.

4) Repeat step 1-3 for every result you get after subtraction.

If you do this you will get kaprekar's constant:6174. It doesn't matter what 4-digit number you start with,you will always get to 6174 and

then get stuck there because 6174 itself gives you a result of 6174. FOR EX:1234 DESCENDING
