I was going through these threads:

- How to find the sum of all elements of a list or a Numpy array?
- How to find sum of array values?
- How to calculate the sum of array values?

And I found different ways to add up two arrays with each other. I have a question in my assignment where I am supposed to add the last axes of an array and I’m perplexed about how to do it, can anyone provide me with its solution?
