Can someone explain "block multiplication" to me? It's not in the book, except in the context of a question as follows:(adsbygoogle = window.adsbygoogle || []).push({});

So the rule is that Matrix [A B] * colum matrix [C D] = [AC+BD] And I am supposed to verify it. but can I just ask how I would go about doing that since I really don't know what block multiplication does or what I'm supposed to multiply? Thanks.
