A maths riddle
This is it,
You can do some operations with a 3-digit no. of different digits, and you should get 1089 every time. Can you?
Answer: You think of any 3-digit number but the digits must be different, say 234.Next step is to twist it and when you twist you gets 432. Now subtract the smaller no. from the bigger no., 432-234 = 198. Now twist the answer, you gets 891. Now add both the nos. 891+198 = 1089!!!
Every time the no. will be 1089!!!!!!!!!!!!!!!!
