Answer 11

Have one NAND gate, take the output of the NAND gate split it into two, into another NAND gate

Question 12

How to turn an OR gate into a NAND gate?

Answer 12

Combine the two inputs for two NAND gates into one then take the output of the two NAND gates and feed them into a third gate

Question 13

How to turn a NOR gate into a NAND gate?

Answer 13

Combine the two inputs for two NAND gates into one then take the output of the two NAND gates and feed them into a third gate, take the output of the third gate, split it into two and feed it into a fourth NAND gate
