Why do you always get 1089?

You always get 1089 with this trick because the steps mathematically force the result: starting with a 3-digit number (digits different, first and last differ by 2+), reversing it, and subtracting always produces a multiple of 99 (like 198, 297, 396, etc.), and when you add any such multiple to its reverse, it always sums to 1089 due to the consistent pattern created by the subtraction.

Why is the answer always 1089?

The Math Behind the Fact:

Since the digits were decreasing, (a-c) is at least 2 and no greater than 9, so the result must be one of 198, 297, 396, 495, 594, 693, 792, or 891. When you add any one of those numbers to the reverse of itself, you get 1089! See the reference for more mathematical magic tricks.
