Penjumlahan, Pengurangan, Pembagian dan Perkalian Bilangan di Borland Delphi 7

Penjumlahan Bilangan dalam delphi ??? Penjumlahan bilangan di delphi yaitu penjumlahan bilangan didalam Program yang kita buat seperti hal nya kalkulator. Kira-kira ada tau tidak gimana cara nya??? untuk yang belum tau saya kasih tau deh.... Open Delphi ANDA !!! Berikut ini saya kasih tutorialnya Penjumlahan, Pengurangan, Pembagian dan Perkalian .

Seperti Gambar dibawah ini :
