Arithmetic operations on NumPy arrays

“

- [Instructor] One of the advantages of working with numpy arrays is that arithmetic operations on numpy arrays are fast and convenient. Note that arithmetic operations on numpy arrays are performed element-wise. I'll be walking through some examples to demonstrate those operations. I'm initializing array A as a one-dimensional numpy array containing the odd integers between one and 20 inclusive. And I'm initializing array B as a one-dimensional numpy array containing the integers one to 10 inclusive. Let's say I want to add the elements of array A to the elements of array B, thereby creating a new numpy array that contains the result. To do this, I can use the addition operator. It would look like this. Now say I want to subtract the elements of array B from the elements of array A, thereby creating a new numpy array that contains the result. To do this, I can use a subtraction operator. It would look like this. Then say…
