$(1)(2$ points$)$ If the product for the following two matrices is elementwise product, what's the

result of the following computing? You should assume broadcasting is valid here, so the

computation is well$-$defined. You may use NumPy to help check the result, but you should know

how to do it manually.

$([1,2],[3,4])([0,1],[2,3])+([4,5])$
