It's possible to add them because they both have 
the same dimensions, 3x2.

So just add their corresponding elements:

%28matrix%283%2C2%2C8%2C8%2C-3%2C3%2C4%2C3%29%29%2B%28matrix%283%2C2%2C3%2C-4%2C-7%2C-5%2C5%2C8%29%29+=+%28matrix%283%2C2%2C%288%29%2B%283%29%2C%288%29%2B%28-4%29%2C%28-3%29%2B%28-7%29%2C%283%29%2B%28-5%29%2C%284%29%2B%285%29%2C%283%29%2B%288%29%29%29=%28matrix%283%2C2%2C11%2C4%2C-10%2C-2%2C9%2C11%29%29 

That's it!
