Stupid number trick (Posted on 2005-12-01) Difficulty: 1 of 5
Take any three different digits.

1. Create every possible two-digit combination.
2. Find their sum.
3. Sum the original three digits.
4. Divide your answer from part 2 by your answer to part 3.

What number do you always get, and why?

What I am thinking | Comment 4 of 9 |
Please note that step 2 asks for every two digit COMBINATION. Now according to the dictionary a COMBINATION of the numbers 1,2,3 and 4 are 12, 13, 14, 23,24, and 34-taking two at a time. a PERMUTATION  of the numbers 1, 2, and 3 are 12, 21,  13, 31,  23, and 32. So I agree with the answer 2. If the people who said 22 are correct, then the second step should say permutation and not combination.
