Answer 7

@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?

Answer 8

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.

Answer 9

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