Issues making the And gate

[kingpinzs]

do I use only one Nand gate and if so how to I invert to output with out using the not gate. If not then using more then one Nand gate works but not sure if that is what it is asking for.

The idea is to build with the chips that you make.  That's the abstraction through encapsulation that the course encourages.  So, use the Not you made as part of the And.

Next you'll make the Or, using some combination of Nand, Not and And.  In chapter 3 you'll be making chips that would take thousands of Nands if you didn't use the chips you make along the way.
