| Gambar 1
Keterangannya :
1 = Button1
2 = Button2
3 = Button3
+ = Button4
4 = Button5
5 = Button6
6 = Button7
- = Button8
7 = Button9
8 = Button10
9 = Button11
* = Button12
0 = Button13
. = Button14
C = Button15
/ = Button16
Sama Dengan (=)= Button17
Nah kalau sudah slesai, Pastekan Codingan Dibawah Ini:
