you're just trying to find the determinant https://www.khanacademy.org/math/linear-algebra/matrix_transformations/inverse_of_matrices/v/linear-algebra--3x3-determinant

@tomo 

Since I want the individual values for I J and K can I just say
I=3   2
   4 -1

and so on for J and K?

Because in the vid he was showing you had to do it a long way for one value.  But since one row is the values I was wanting to find I was thinking this would work.

woah, wait, all I need is the u*v value.
