I know you're supposed to use the chain rule for this, but it's been a little while since I've used it; so if you could show me how you got there and explain to me over again what the chain rule is, that'd be awesome.

Use 9 numbers, each of them only once, 1 through 9, and you had 9 spaces arranged within a square shape, with 3 on top, 3 in the middle and 3 on bottom. 5 is the middle of the center spaces with 4 unfilled spaces surrounding it. finally they must, and I mean MUST, equal 15 in every direction.
