Angular CLI Typescript Angular Framework SCSS for styling using Flex
Angular framework was used because you can easily generate an Angular project using Angular CLI commands. With few lines of commands, you can create an app and run using your dev server. Since this exercise focuss more on CSS styling, I used SCSS for styling using flexbox container to demonstrate that the div section can be containerized and segreate each section within their container. The whole calculator resides inside the main container and the display and input buttons resides in the sub container.
