-2 is at centre of the square

Interseting that -2 is at the centre, given that -2 isn't one of the numbers you're supposed to use!

OK, so lets assume that the subject of this question has a typo having left -2 out by mistake. Here's a hint: The numbers to use are like a "standard" magic square except that the numbers 1 through 9 are replaced by -10 through 6. Which is as if each entry of a standard magic square is replaced by 2 times the number minus 12.
