Because only 2008-0 = 2008, so the sum of the middle seven numbers should be equal to 0. For continuous integers, the middle should be 0, the first three should be negative, and the last three are positive, so the answers are - 3, - 2, - 1, 0, 1, 2, 3
-3 - 2 - 10 1 2 3 or 3 2 1 0 - 1 - 2 - 3
2008-(-3)-(3)-(-4)-(4)-(-10)-(5)-(5)=2008
3 2 1 0 -1 -2 -3
