yeah youre right
there are actually a formula into it, i never realize that
-1 0 1
2 3 4
5 6 7
8 9 10
11 12 13
14 15 16
17 18 19
20 21 22
23 24 25

this is how i did it and i multiply them each row
and result in this

-1 0 1 0
2 3 4 24
5 6 7 210
8 9 10 720
11 12 13 1716
14 15 16 3360
17 18 19 5814
20 21 22 9240
23 24 25 13800
26 27 28 19656

where the fourth coloumn is equal to the multipication of all the number in the row.
