DeMorgan's Law

Name	Statement
Associative Law	$A\cdot B\cdot C=(A\cdot B)\cdot C=A\cdot (B\cdot C)$
Distributive Law	$A\cdot (B+C)=(A\cdot B)+(A\cdot C)$
Commutative Laws	$A\cdot B=B\cdot A$
	$A+B=B+A$
	$A\oplus B=B\oplus A$
DeMorgan's Law (1)	$\overline{A+B}=\bar{A}\cdot \bar{B}$
DeMorgan's Law (2)	$\overline{A\cdot B}=\bar{A}+\bar{B}$
