There are few boolean algebra rules to be followed to while solving problems Examples of these particular laws of Boolean algebra, rules and theorems for Boolean Algebra are given in the following table. Using the above laws, we can simplify the given expression: (A + B) (A + C)

Boolean expressions are simplified to build easy logic circuits. Laws of Boolean Algebra Boolean algebra has a set of laws or rules that make the Boolean expression easy for logic circuits. Through applying the laws, the function becomes easy to solve.

Boolean Laws. There are six types of Boolean Laws. Commutative law: 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.

In boolean logic, zero (0) represents false and one (1) represents true. In many applications, zero is interpreted as false and a non-zero value is interpreted as true. Mention the six important laws of boolean algebra. Stay tuned with BYJU’S – The Learning App and also explore more videos.
