Build a CodePen.io app that is functionally similar to this: https://codepen.io/freeCodeCamp/full/wgGVVX. A list of user stories for passing the test can be found here. The layout of the calculator is based on the Samsung/Android calculator, a screenshot can be seen here.

Follow the steps below to run the project:

1. make sure you have NPM installed
2. clone the project using git clone https://github.com/electrovagance/FCC-Calculator.git in your console
3. install yarn using yarn install in your console
4. start the development server with yarn start
5. app will be hosted locally (i.e., http://localhost:3000 in your browser)

• Make calculator responsive
• Improve layout of buttons
• Come up with a solution for large/long input (scrolling display?)
• Add more calculator features
