Di bawah ini script aba-aba kalkulator untuk menciptakan aplikasi dengan basic yang akan agan terapkan pada mata pelajaran kuliah, kiprah kuliah, maupun pola skripsi bagi anak it.

Namun bila tidak suka dengan warna atau kotak kotak tampilan kalkulator menyerupai demo di atas, agan dapat edit edit dengan html pada post blog dengan perlahan, baik dari gradasi warna, bentuk dan lain sebagainya.
Cukup sekian artikel yang aku bagikan script aba-aba kalkulator ini, supaya membantu.
