But if you did that, how would the determinant be found? That makes no sense how that can be found if it is in the rows and columns like that. So in thousands, would the first be 10000,000?

the result is only the sum of cr*first column and cp*second column

Right, so what would that be? In thousands? Because that is what it is listed as in the problem copied

okay. so what I am going to do (just to make sure I understand the drawings) 1. 500*200, 500*15, 500*5 2. 600*30, 600*5, 600*2 Then add the results of 500*2 and 600*30 together, and so on? Is that correct?

multiplication by left is linear combination of columns, and by right is linear combination of rows

I'm sorry I don't quite understand that. Can you put in smaller terms? Like I said, math is not my forte.
