A basic calculator might seems a straight forward application at first. But as you start implementing it you might come across some rather unexpected use cases that you might have not thought about previously that need to be solved. For part $1$ of the project, you are asked to create a text based calculator to perform the same basic functions as a standard calculator. The following image will illustrate the required functionality of your calculator. Submission

Part one of the project is required to be written in Visual Studios and the C# programming language to create a console application. Elegance of your interface $($menu system, prompts, error handling$)$
