RE: General calculation type question

I know this is probably going to be a dumb question, but I haven't been able to successfully read inputs from a keypad. They keybad works by connecting 2 inputs TOGETHER when a key is pressed on 6 pins. I know how to read a pin when its pulled high through a resister out to V+ and if its low V-. But if they connect together what am I supposed to do to read this state?
