Write a function called operations that takes three inputs: a real number c $($a float$)$ and two matrices A and B

$($numpy arrays$).$ It should return a dictionary that has seven key$-$value pairs:

shape: the shape of A

$($as a tuple$)$

scale: A

scaled by c

$($as a numpy array$)$

sum: A

plus B

$($as a numpy array$)$

difference: A

minus B $($as a numpy array$)$
