To see the first absorption law, x ∧( x ∨ y ) = x , start with the diagram in the middle for x ∨ y and note that the portion of the shaded area in common with the x circle is the whole of the x circle. For the second absorption law, x ∨( x ∧ y ) = x , start with the left diagram for x ∧ y and note that shading the whole of the x circle results in just the x circle being shaded, since the previous shading was inside the x circle.
