Simple Calculator Built with React

This project was bootstrapped with Create React App.

To run the project run npm install and npm start

Calculator App

This react application implements a simple calculator. Calculator has following component hierarchy.

APP

• Screen (Input Box + Results Box)
• Input Components (dot,0-9)
• Command Components (clear, divide, multiply, minus, add, equals)

Our state will live in App.js

Use Cases:

1. Enter Number
2. Enter Command (When a command is hit, the input box clears but previous data is saved.)
3. Enter Second Number -> calculate results
4. Enter Second Command. (If the command is )

State: We will need state to store all the numbers and operations the user enters. They get calculated immediately after a new command is entered.

Approach

• Since state will probably need to be tweaked lets start there.
• I need a simple Number Component and a Command Component.
