According to the principle of duality, a true boolean statement or expression can be converted to its dual form by replacing the "0"s in the statement or in the expression with "1"s, and vice versa and by replacing the "+"s in the statement or in the expression with "."s, and vice versa.
For Example;
The dual form of (X+Y)(X + Z).(Y + Z) is
(X.Y)+(X.Z)+(Y.Z).
In the above dual expression, all the "+"s were replaced by "."s, and vice versa.
