FINISHED :D IMPORTANT: I plan on fixing this, but right now, the numbers will be added left to right. For example, if the number says 00000, and I click 6, it will say 60000. Click 0 to skip that digit. In the future, in these cases, it will say the digit as 00006. I'm trying, but this is hard. IMPORTANT: The 'Edit#' show which digit is being edited, and the 'What you are editing' displays the number being edited. Buttons: Numbers 0-9 (Red Buttons) = Will add the number you click to the digit being edited. Operations (Blue Buttons) = Will change the operation used to solve the equation. Clear (Green Button) = Will wipe all numbers, and set the answer back to 0. Gray Circle = Add one to the answer, only if the equation has been finished.
