This is just a normal calculator which is available in GooglePlay store. I set the price to 500 baht because I know nobody will buy it XD

I spend 3 months on it as it was my first project in Xamarin.forms. (I did not know how to use Github then, hence 20 commits)

The calculator could be made with better methods and conventions but as I have mentioned I was learning how to use MVVM in Xamarin.forms But hey it is working so as we say in software development "if it is working, let it be" :D
