This is in C#

Create a SINGLE method that each of the buttons call when clicked

The method will need to return a number back to the calling method.

The method will need to receive 3 parameters.

Two of which are the numbers (not strings) from the textboxes.

The third parameter is to represent the operation to be preformed

The operations performed values are provided for you as constants in the project and named such. Look for the comment in the code.

When you call your method, one parameter should be one of those constants.

When in the method, you will use one of the parameters that you sent into the method to determine which operation to do. This will be achieve by use of control code. Think decision diamonds from flow charting.

Have a single return point in the method. Do not return in the middle, only at the end
