Let's practice slicing numpy arrays and using NumPy's broadcasting concept. Remember, broadcasting refers to a numpy array's ability to vectorize operations, so they are performed on all elements of an object at once.

A two-dimensional numpy array has been loaded into your session (called nums) and printed into the console for your convenience. numpy has been imported into your session as np.
