You'll earn bonus points if you can modify the program so that the arithmetic practice is on the product of two integers (instead of the sum of two integers), and the keyboard input to quit the program is "stop". In order for this to work correctly, I took the source code and did the following: 1. I switched the "plus" to "times" in the window.prompt sections. 2. I then switched "num1 + num2" to "num1 * num2" and tested the code in the preview window to see if it would multiply the numbers correctly.  3. Next, I switched (inputValue! = -1) to (inputText != "stop") this != allows the value to return the stop window.prompt if they are not equal.  I no longer want this to be an      integer, so I had to remove the Value in the inputValue and change it to Text.  I also discovered that you actually have to put stop in quotes or it still won't work! 4. I then switched -1 in the window.prompt sections to stop.
