Boolean or Logic Operators

 Parenthesis must always be used to separate out the different boolean operators in an expression.

carry <= a and b or a and c or b and c;--

carry <= (a and b) or (a and c) or (b and c);--

The only exception is the not operator

zout <= not a and b;    -- equivalent to

zout <= (not a) and b;
