Welcome! Let's explore Basic Array Operations with NumPy, a powerful library for data analysis, machine learning, and scientific computing. We'll seek answers to questions like: How can arrays interact with one another? Can they be added, subtracted, multiplied, and divided? And if so, what insights can we gain from these operations?

"Basic Array Operations" refer to mathematical operations like addition, subtraction, multiplication, and division that are performed on arrays in an element-wise manner.

Consider two arrays representing yesterday's and today's temperatures. To find the change in temperature, you would subtract the yesterday array from the today array.

Ensure the arrays have the same shape before performing these operations!

In NumPy, the + and - operators perform addition and subtraction operations, respectively, between arrays in an element-wise fashion.

Let's say you have arrays of products sold in two consecutive months. To find the total sales, simply add the arrays:
