This is an exercise on MVVM (specifically with Prism).
There's a complete function to ADD two numbers.
You are tasked to create similar functions for subtract/multiply/divide.
Ensure that a divide by zero is not possible to do.
Follow the template in the View and the ViewModels to finish this exercise. You should pass 100% of tests afterwards.
This exercise is purposefully more open ended than the last exercises. For documentation on the prism library,
