I came up with 0 being the magic square, is this the correct answer you came up with.

You can't just pluck an answer out of the air. How did you come up with "0"?

Msephus - If you have you come up with an arrangement of the numbers that achiecves the magic square then you wouldn't need our confirmation that your answer is correct. However as a hint, consider that the 9 numbers you have been given are all evenly spaced 4 uniots apart, and so can be mapped in a linear way to the digits 1 through 9, where -16 maps to 1, -12 to 2, -8 to 3, and so. If you know how to solve a classic magic square using numbers 1 through 9 you can map the numbers you have been given directly onto that solution.

How do you solve 3x3 magic square using -4,-3,-2,-1,0,1,2,3,4

Same way you do a traditional magic square using the numbers 1 through 9, except subtract 5 from each entry. Thus if you know where the number 8 goes in a traditional magic square, that's where 8-5=3 goes in this "shifted" version.
