NAND gates used to make different logic gates

[@Konic_and_Snuckles]

What about XOR and XNOR gates made up by NAND gates?

[@kidus_3044]

You can simplify XOR and XNOR as
A xor B = A'B or AB'
A xnor B = (A'B or AB')' = A'B' + AB

Very helpful thanks

Dual input NAND gates are also handy for making set/reset latches. The first CPU I ever worked on was made 90% of dual input NAND gates, Of course it had magnetic core memory.
