One thing we notice here is that our variables themselves are not called number1 and number2! In fact, they can be called anything they want!

In this example, the real variable names were `num1` and `num2`, but JavaScript knows that in our function body when we type `number1` that we just mean the first argument passed to the function.
We now know types of variables in JavaScript and the operations we can do on them, as well as how to write functions in JavaScript with multiple function arguments! We are seriously making progress in having the skills to develop a well-functioning web application!
