Problem Statement

Pada pertemuan ke lima, ditugaskan untuk mencoba kotlin dengan latihan membuat aplikasi kalkulator sederhana, yang mengimplementasikan operasi aritmatika dasar. Yakni penjumlahan, pengurangan, perkalian, dan pembagian. Adapun referensi yang saya gunakan sebagai referensi utama dari penugasan ini dapat diakses pada link berikut
