You can put this solution on YOUR website!
.
Instead of doing these examples for you (or, better to say, INSTEAD of you),

I'll better formulate two rules that will help you to make it on your own: 

1.  To take a multiple of a matrix (like 2A) means to multiply EACH its element by the given factor.


2.  To take the SUM of two matrices (like A + B) means to take the sums of the components/elements in each position.

Now you are ready/you are prepared to do it on your own.
