Question

How do you multiply matrices given `A=((0, 2, 1), (-5, -1, 0))` and `B=((1, -4), (0, 1), (5, -1))`?

Answer 1

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

Explanation:

If you have the multiplication of two matrices

`((a,b,c),(d,e,f))*((k,l),(m,n),(p,q))`

`=((ak+bm+cp,al+bn+cq),(dk+em+fp,dl+en+fq))`

Therefore,

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

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