I've attached a scan of a problem I'm working on. I need to change this circuit to all NAND gates. I have no clue if what I've done so far is correct. It seems like to go to NAND you have to get rid of the +'s. Is this even close to correct the way that I've done it? Once I have converted this to a NAND circuit then I need to draw it. I would greatly appreciate any advice.
