Math Trick :)

Take any three digit number in which the first and last number differ by more than one i.e. 335 would be O.K. but not 333, or 332.

Reverse this number

Subtract the smaller number from the larger.

Add this answer to the same number reversed and the answer is ALWAYS 1089.

Example 1:-

335 Reversed = 533

533 - 335 = 198

198 + 891(198 reversed) = 1089

Example 2:

932 reversed = 239

932 - 239 = 693

693 +396 = 1089
