Calculator
This app simplifies all the mathematical needs from basic to complex functions. It allows the user to save and reference his previous calculations at any time. Plus, it can easily handle EMI calculations, compare results, and share them with other apps

Architecture
The architecture of this application relies and complies with the following points below:
- A single-activity architecture, using the Navigation Components to manage fragment operations.
- Pattern Model-View-ViewModel(MVVM) which facilitates a separation of development of the graphical user interface.
- Android architecture components which help to keep the application robust, testable, and maintainable.
