Question

How do you compute the matrix AB given `A=((3,0),(-1,5))` and `B=((0,4,-1), (-3,3,-5))`?

Answer 1

The answer is `=((0,12,-3),(-15,11,-24))`

Explanation:

To compute the matrices, we use the following :

`((a,b),(c,d))((p,q,r),(s,t,v))=((ap+bs,aq+bt,ar+bv),(cp+ds,cq+td,cr+dv))`

Therefore,

`((3,0),(-1,5))((0,4,-1),(-3,3,-5))=((0,12,-3),(-15,11,-24))`
