Simple Calculator

This is a very basic calculator. I have uploaded the code. There are actually 4 files.
Main.lua / Characters.lua / HandleTouch.lua / Buttons.lua (class).
I have put all 4 files in the same file but you can easily figure out each of these 4 files.
I know there are still some bugs in it but i hope everyone will like it.
Feel free to fix the bugs if you like.
