Have you tried reading the notes you took in class?

We have an informal policy here of not doing people's homework for them.

If your notes aren't up to scratch, you could try some actual research, ir, if that fails, you could even talk to your "prof" and ask for advice.

Sure, if you show the input / output truth table for a NAND gate,

I will show how to wire a 0101 to a 7seg 5 acdfg active low = common anode LED.

From that hint you can understand how to do the rest..
