Fixed subtraction issue, added corrected enter functionality where it will repeat the last function again. You can even change the sign to utilize the last value. Signs will no longer stack and can only be utilized once. Click 5 plus plus plus will not do anything until you enter another number and press enter or another sign. In other words...this sh\ works. Sorry for no comments though. I can add them some other time.
