Are you an aspiring software developer who wants to build real applications? Most people learn to code but don't build any real-world applications with their skills. I know that feeling because I have been there. That's why I've made this course for you, which will help you build desktop applications using Python. 

Building apps with Python is easier than you think, thanks to the Tkinter library. If you know Python and you want to take your skills to the next level by building some cool apps, then this is the right course for you. In this course, you will learn how to create desktop applications using the Tkinter library of Python.

You don't need to be an expert-level Python programmer. All you need is a basic understanding of Python programming. 

If you're ready to build your first app, join me on this journey. Together, we will create some cool apps that will help you become a better software developer.

Now we will implement other mathematical functions using the OptionMenu widget. This will allow the user to choose the operation they want to perform.

## Adding an OptionMenu widget

Let’s create a label and an OptionMenu with four options: "add", "subtract", "multiply", and "divide".

opLabel = tk.Label(text = "Select the Operation: ")
opLabel.grid(column=0,row=2)

myOption = tk.StringVar(window)
myOption.set("Select")
opMenu = tk.OptionMenu(window, myOption, "Add","Subtract", "Multiply", "Divide")
opMenu.grid(column=1,row=2)

Now, the users can select the operation that they want to perform.

## Updating the `addNumbers()` method

We need to read the option that the user selects and perform the corresponding calculation. 

To do that, let’s update the `addNumbers()` method. First, let's update the name of `addNumbers()`  to be `mathOperations()`, since it will now perform multiple calculations. 

We can read the option that the user selects using the `get()` method. We will use an `if-elif-else` block to check the options and perform the corresponding operations.
