How to design with using several two input NAND gates to implement the function F=A+B+C............
Double NOT the function, and use DeMorgan's theorem to change the expression from OR to AND type. If you tie the inputs of a NAND gate together you get a NOT gate.
design it with OR gates first then redesign it with NAND.
That is essentially what you are doing with DeMorgan's theorems.
