Always End With 1089

Add two number together and always end with 1089.

Here is How:

-Pick a three digit number. The three numbers used must be different.
i.e. 123


-Reverse that number. 123 becomes 321


-Take the smallest three digit number from the largest.
321 - 123 = 198


-Take the answer and reverse that number.
198 becomes 891


-Add that number to the answer of the subtraction.
891 + 198 = 1089

The answer will be 1089



A Little Footnote
But I ended with 198 not 1089.
This happens if you pick a number like 546. Try to pick consecutive numbers like 123, 345, 765 etc.
If it does happen, it is not a problem.
Just repeat the stages again starting from 198.
