Boolean algebra is one topic where most students get confused. But it is pretty simple if you understand the logic behind it. Boolean algebra is the branch of algebra wherein the values of the variables are either true or false, generally denoted by 1 and 0 respectively. Whereas in elementary algebra we have the values of the variables as numbers and primary operations …

According to George Boole symbols can be used to represent the structure of logical thoughts. This type of algebra deals with the rules or laws, which are known as laws of Boolean algebra by which the logical operations are carried out.. There are also few theorems of Boolean algebra, that are needed to be noticed carefully because these make calculation fastest and …

Similar to these basic laws, there is another important theorem in which the Boolean algebraic system mostly depends on. That is De Morgan’s law. This can be also known as De Morgan’s theorem. This law works depending of the concept of Duality. Duality means interchanging the operators and variables in a function, such as replacing 0 with 1

There are theorems that govern the structural logical laws of Boolean algebra. In the same way, there are postulates to know the possible results in different combinations of binary variables, depending on the operation carried out. Sum (+) The operatorORwhose logical element is the union (U) is defined for binary variables as follows: 0 + 0 = 0. 0 + 1 = 1. 1 + 0 = 1 . 1 + 1 = 1. …

Each of the laws and theorems of Boolean algebra, along with a simple explanation, is listed below. LAW OF IDENTITY - a term that is TRUE in one part of an expression will be TRUE in all parts of the expression (A = A or A = A). COMMUTATIVE LAW - the order in which terms are written does not affect their value (AB = BA, A+B = B+A). ASSOCIATIVE LAW - a simple …

Boolean Laws. There are many theorems (laws) that can be derived from the axioms. A few are listed here. Idempotent laws: p^p = p and p_p = p. Absorption laws: p_(p^q) = p and p^(p_q) = p. Involution law: :(:p) = p. 2.

A = 0 The basic Laws of Boolean Algebra that relate to the Commutative Law allowing a change in position for addition and multiplication, the Associative Law allowing the removal of brackets for addition and multiplication, as well as the Distributive Law allowing the factoring of an expression, are the same as in ordinary algebra.

Description of the Laws of Boolean Algebra Annulment Law – A term AND ‘ed with a “0” equals 0 or OR ‘ed with a “1” will equal 1 A. 0 = 0 A variable AND’ed with 0 is always equal to 0 A + 1 = 1 A variable OR’ed with 1 is always equal to 1
