In this exercise, youll create a a Visual C# program using a Windows form app that accepts two operands and an operator from the user and then performs the requested operation.

1. Start a new project named SimpleCalculator in the Extra Exercises\Chapter 06\SimpleCalculator directory.

2. Add labels, text boxes, and buttons to the default form and set the properties of the form and its controls so they appear as shown above. When the user presses the Enter key, the Click event of the Calculate button should fire. When the user presses the Esc key, the Click event of the Exit button should fire.

3. Code a private method named Calculate that performs the requested operation and returns a decimal value. This method should accept the following arguments:

4. Create an event handler for the Click event of the Calculate button. This event handler should get the two numbers and operand the user enters, call the Calculate method to get the result of the calculation, display the result rounded to four decimal places, and move the focus to the Operand 1 text box.

5. Create an event handler for the Click event of the Exit button that closes the form.

6. Create an event handler that clears the Result text box if the user changes the text in any of the other text boxes.

7. Test the application to be sure it works correctly.
