Why can we normalize an array in the way that No.22 do?

I know what np.mean() does and the process of np.std(), but I couldn't figure out why we can do a normalization in the way that combine them together.

Why does it works normalize an array like Z = (Z - np.mean (Z)) / (np.std (Z)) use dividing?

It's just a formula in math here, and doesn't have much to do with numpy.
