Beginners Created: January 17, Size: Download the file. Logical ANDing of the two or more variable is represented by writing a dot between them such as A.

Sometime the dot may be omitted like ABC. Any binary operation which satisfies the following expression is referred to as commutative operation. Commutative law states that changing the sequence of the variables does not have any effect on the output of a logic circuit. This law states that the order in which the logic operations are performed is irrelevant as their effect is the same.
