My WIP CalculatorCurrently It can only add or subtract two 2 digit numbersTo input an equation, click on the keyboard to select it, and type your equation, example: 9+4 or 9-4After this, wait for a few seconds and the answer should appear on the 3 7 segment displays on the very right
Now there are some things I would LOVE some help with if you could1.  I need a way to convert 4 digit numbers into raw binarySo basically I need a way convert either the BCD format of, say, 9292 into a raw binary 9292OR I need a way to combine a raw binary 92 and another raw binary 92 into again a raw binary 9292I could multiply one of those sets by 100, but I dont know how to do that:( (might also need help with that...)
2. For a larger memory, what bit size should I use per entry, and how can I make it know that a memory already has something stored and to use another oneAnd a problem with that, how can I make it know which memory addresses store the information it needs to use?Anyways, hopefully thats all for now, please if you can reply in the comments or something, as im a bit lost here:)Thanks!
