yeah, there's something missing in the instructions regarding the first Nand gate. I understand how a NAND Gate is constructed but I can't figure out how to combine the outputs of the two relays in this tool


A nand B = not(A and B)

One of the relays gives you "A and B". The other gives you "A and not B". "A and not B" with A = 1 is just "not B".


The components that are available is usually a hint. Have you used both types?
