Yeah basically. In binary, multiplication is an XNOR operation.

00 = 1

01 = 0

10 = 0

11 = 1

XNOR does not distribute over AND or any other binary operators (try 0 XNOR (0 AND 1)), nor does it have a multiplicative identity, so it's not really multiplication in a way that's useful.

0*0 = 1? I've always hear it as being the output of AND

For balanced binary [-1, 1] yes. -1*-1=1

That makes sense, thanks!
