Question

Given this general matrix multiplicaiton problem, explain how you would know where to place the answer in matrix [C] that corresponds to the work you did with row vector 2 from Matrix [A] and column vector 1 from matrix [B].

Answer 1

Answer:

  the row and column descriptors identify the row, column of the sum of products.

Step-by-step explanation:

The position of the product is at the same row and column as the row vector and column vector you're working on.

The work you did with row vector 2 from Matrix [A] and column vector 1 from matrix [B] will show up in row 2, column 1 of matrix [C].
