No.

In your example \$x*y\$ is being defined to mean the binary operation: \$x+y+xy\$. (Presumably for this reason you have the right to solve part problem around such a binary operation.)

In one more problem you can be told \$x*y\$ method something else. Or in basic we can say "Let \$*\$ be a binary operation" and we won"t understand anything around what \$x*y\$ is; just that that is part binary operation.

In binary logic \$+\$ refers to OR and also \$cdot\$ refers to AND.

You could additionally use alternate notation \$xlor ylor(xland y)\$ however it is tantamount to basic \$xlor y\$ or \$x+y\$ in the origninal notation.

Assuming the is really a reasonable operation, I do not see the objective of defining \$*\$ if that is the very same thing as \$+\$ or possibly this is th epurpose that the practice to show they room the exact same rules.

Anyway, I periodically saw \$*\$ being supplied for NAND i.e. \$lnot(xland y)\$ or \$(xy)"\$ in both notations.

But this is not the instance here, room you details about the an interpretation of \$x*y\$ ?
