Cara Membuat Kalkulator Menggunakan OOP

Halo teman teman di panduan kali ini saya akan membahas mengenai Cara Membangun Kalkulator Menggunakan OOP, seperti yang kita ketahui bahwa kalkulator berfungsi selaku alat bagi mengerjakan perhitungan, di panduan Cara Membangun Kalkulator Menggunakan OOP, kita akan membahas perhitungan seperti tambah (+), kurang (â€“), kali

, dan untuk (/).

Oke teman teman kita seketika saja di pembahasannya mengenai Cara Membangun Kalkulator Menggunakan OOP.

Langkah pertama-tama yang mesti teman teman lakukan yaitu silahkan bikin sebuah folder baru yang bernama kalkulator, didalam folder tersebut nanti kita akan bikin sebuah file baru dengan nama index.php. dan silahkan teman teman simpan script dibawah ini di file index.php

<?php<br />
