When multiplying n-dimensional arrays it's important to know what type of multiplication you want to do.

• When you want to do element-wise multiplication np.multiply() works the same way as using the * operator
• However, sometimes you want to take the dot product of two arrays, in which case you should use np.dot()
• The final common way to multiply n-dimensional arrays is by using np.mmult() which will return the matrix product of the arrays
