This project goes in tandem with the SOLIDCalculator microservice. Can also work with the lite version of the microservice, SimpleCalculator.

Run ng serve in the terminal.
Navigate to http://localhost:4200/.
The application will automatically reload if you change any of the source files.

Run ng test.

Input is only possible through the buttons.
History is saved in the App, not in the microservice, this was to simplify the project and thinking of actual usage for a calculator.
The calculate(=) button is disabled until a valid calculation is possible.
This is a relatively complex solution to an otherwise simple problem.

• Instead of using a string, this could have been done with a stack.
• The history could have been saves in the Microservice, and not in the App.
• Input could be possible through the keyboard, and direct intput to the relevant field.
