Hi, I have doubt regarding Logic on how it is able to performed this . array_a = np.array([[7,8,9]]) array_a Shape 1*3 array_b= np.array([[1,2,3],[4,5,6]]) array_b shape 2*3 Can you please explain how it is able to perform Matrix sum and multiplication with 1*3 and 2*3 shape .I thought m*n and n*p only when these conditions are satisfied, then only operations are possible As I can see operation is happening here so just wanted to understand in bit more detail mathematically. Regards, Manas
