If you haven’t read Simple MVC framework tutorial Part 1, I suggest you read it here.
In the second part of Simple MVC framework tutorial, I will extend the calculator application to a fully working one.
In this tutorial, I will show you how to build a very simple calculator application using MVC architecture pattern. This calculator only has addition and subtraction, and you will be able to extend this basic application by adding multiplication and division as exercise yourself! Before we start, I would like to talk briefly what MVC is and why we use it.
