One good fact about the number 1089 is: pick a 3 digit number (they cannot be the same) i.e 123 reverse it 321 take the smallest amount from the largest 321-123=198 take the answer and reverse it 891 then add that number to the answer of the subtraction 891+198=1089 no matter what 3 numbers you use you will always end up with 1089 for the answer.
