## Overview

Emo Cal is a small web calculator: a visitor opens the calculator page, enters two integers and an operator, then submits the calculation and receives operation details as JSON. The documented routes and response shape establish the main flow. The frontend JavaScript and calculation implementation were not sampled, so their internal wiring is not expanded here.

Main entry points: [`app/Http/Controllers/Calculator.php`](https://github.com/mahmudur26/emo-cal/blob/development/app/Http/Controllers/Calculator.php) (Calculator controller), [`public/index.php`](https://github.com/mahmudur26/emo-cal/blob/development/public/index.php) (HTTP entry), [`routes/web.php`](https://github.com/mahmudur26/emo-cal/blob/development/routes/web.php) (Web routes), [`resources/views/calculator.blade.php`](https://github.com/mahmudur26/emo-cal/blob/development/resources/views/calculator.blade.php) (Calculator page)

- [HTTP kernel](https://github.com/mahmudur26/emo-cal/blob/development/app/Http/Kernel.php): `app/Http/Kernel.php`
- [Route provider](https://github.com/mahmudur26/emo-cal/blob/development/app/Providers/RouteServiceProvider.php): `app/Providers/RouteServiceProvider.php`
- [Web routes](https://github.com/mahmudur26/emo-cal/blob/development/routes/web.php): `routes/web.php`

### Calculator

- [Calculator controller](https://github.com/mahmudur26/emo-cal/blob/development/app/Http/Controllers/Calculator.php): `app/Http/Controllers/Calculator.php`
- [Calculation JSON](https://github.com/mahmudur26/emo-cal/blob/development/app/Http/Controllers/Calculator.php): `app/Http/Controllers/Calculator.php`

### User interface

- [Calculator page](https://github.com/mahmudur26/emo-cal/blob/development/resources/views/calculator.blade.php): `resources/views/calculator.blade.php`

### Other components

- **Visitor**

## Connections

- Visitor → HTTP entry: sends request
- HTTP entry → HTTP kernel: handles request
- Route provider → Web routes: loads routes
- Web routes → Calculator controller: dispatches route
- Calculator controller → Calculator page: renders page
- Calculator page → Visitor: presents form
- Visitor → HTTP entry: submits operands
- Calculator controller → Calculation JSON: returns result
- Calculation JSON → Visitor: delivers result
