+23245 A very interesting question ...
The integers: ..., -3, -2, -1, 0, 1, 2, 3, ...
If you arranged them as: 0, 1, -1, 2, -2, 3, -3, 4, -4, ...
and added them this way: (0) + (1 + -1) + (2 + -2) + (3 + -3) + ...
you would get: 0 + 0 + 0 + 0 + ... = 0
but, if you added them this way: (0 + 1) + (-1 + 2) + (-2 + 3) + (-3 + 4) + ...
you would get: 1 + 1 + 1 + 1 + 1 + ... which tends to positive infinity
and, if you added them this way: (0 + -1) + (1 + -2) + (2 + -3) + (3 + -4) + ...
you would get: -1 + -1 + -1 + -1 + ... which tends to negative infinity
So, there is no particular sum -- no sum ...
You might want to try to rearrange the integers to get other "answers" ...
