Those that take 4 inputs and 3 inputs? How is that possible can a NAND gate take 3 inputs and AND gate 4 inputs?

@JOhn : It can be possible and it can be implemented using P-MOS and N-MOS together in a circuit i.e. what is called C-MOS. There we can implement Three Terminal NAND GATE . It is a universal gate which is used commonly so can proceed further.

What does the top row of gates do? Don't understand.
