This project is a simple calculator created using React. The user interface is inspired from the Calculator app on iPhones. It has buttons for numbers and operators, with a display showing the input and results.
The calculator can perform the four basic mathematical operations: addition, subtraction, multiplication, and division.
Running the application requires the runtime environment Node.js and npm. Make sure these are installed on your computer.
First, in order to run the application, node_modules folder needs to be installed locally. There is a package.json file inside the project's main folder. Type the following command inside a terminal, with the terminal pointing to the directory that contains the package.json file.
npm install
This command will install the node_modules folder with all the npm packages necessary for running this application. Once the command is finished, the app can now be served locally by running the following command:
npm start
This will end up with the following output in the terminal:
Compiled successfully!
We now have the application running on localhost:3000. To view the application, open a browser with the address bar pointing to http://localhost:3000, and now you can start exploring the calculator!
