Question

How do you multiply `((0, 2, 1), (-5, -1, 0))` with `((1, -4), (0, 1), (5, -1))`?

Answer 1

The answer is `=((5,1),(-5,19))`

Explanation:

let's do the matrix multiplication
You multiply horizontally for the first matrix and vertically for the second matrix.

`((0,2,1),(-5,-1,0),( , ,))` `((1,-4, ),(0,1, ),(5,-1, ))`

`=((0+0+5,0+2-1),(-5+0+0,20-1+0))`

`=((5,1),(-5,19))`
