# what is commutative law in boolean algebra

The basic Laws of Boolean Algebra can be stated as follows: Commutative Law states that theinterchanging of the order of operands in a Boolean equation does not change its result. For example: OR operator → A +B = B + AND operator → A *B = B * Associative Law of multiplication states that the AND operation are done on two or more than two variables. For example:

## What is the commutative law of multiplication?

For two variables, the commutative law of multiplication is written as: This law states that the operation can be performed in any order when the variables priority is same. As ‘*’ and ‘/’ have same priority. In the below diagram, the associative law is applied to the 2-input OR gate.

## How is Boolean algebra different from mathematical algebra?

Boolean algebra differs from the mathematical algebraic system with respect to the operations done on its variables. Since this is a new system, there are some new rules and laws that apply.

## What is boolean algebra?

Boolean Algebra is the mathematics we use to analyse digital gates and circuits. We can use these “Laws of Boolean” to both reduce and simplify a complex Boolean expression in an attempt to reduce the number of logic gates required. Boolean Algebra is therefore a system of mathematics based on logic that has its own set …

## Which law of Boolean algebra allows the removal of brackets?

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.

## What is the absorptive law?

Absorptive Law – This law enables a reduction in a complicated expression to a simpler one by absorbing like terms.

## What are the algebraic laws of Boolean?

0 . 0 = 0 A 0 AND’ed with itself is always equal to 0. 1 . 1 = 1 A 1 AND’ed with itself is always equal to 1.

## What is the order in which two variables are OR’ed?

A + B = B + A The order in which two variables are OR’ed makes no difference. Double Negation Law – A term that is inverted twice is equal to the original term. A = A A double complement of a variable is always equal to the variable. de Morgan’s Theorem – There are two “de Morgan’s” rules or theorems,

## What are the symbols for a closed circuit?

As well as the logic symbols “0” and “1” being used to represent a digital input or output, we can also use them as constants for a permanently “Open” or “Closed” circuit or contact respectively.

## Which law allows the removal of brackets from an expression and regrouping of the variables?

Associative Law – This law allows the removal of brackets from an expression and regrouping of the variables.

## What are the main operations of Boolean algebra?

The main operations performed on Boolean algebra are conjunction (Boolean AND ), disjunction (Boolean OR) and negation (Boolean NOT ).

## What is Boolean algebra?

Boolean algebra is a branch of algebra wherein the variables are denoted by Boolean values. True (also represented by a 1) and False (also represented by a 0). That’s it. Those are the only two values we’ll deal with in Boolean algebra or digital electronics for that matter. Boolean algebra differs from the mathematical algebraic system …

## What is the result of an AND operation?

An AND operation results True if all its variables in the Boolean expression are True. If either of the variables in the expression is False, the result is False.

## How to get the dual of a Boolean expression?

The dual of a Boolean expression can be obtained by replacing all the AND operators to OR and all the OR operators to AND, and by replacing all the binary values, i.e. all the 0 with 1 and all the 1 with 0 in the equation.

## How many statements are there under the Distributive Laws?

There are two statements under the Distributive Laws:

## How does reducing the size of the circuitry affect the speed of the circuit?

Additionally, reducing the size of the circuitry also increases the speed of the circuit.

## What happens if you use the NOT operation twice on a variable?

The law basically says that if you use the NOT operation twice on a variable, you get back the original variable without any change in its value. Consider a variable A. Let the negation of A, i.e. A’ be given by Y. If we perform the negation operation on Y, we get back the variable A.

## What happens if the input variable is 0?

Let’s suppose; we have an input variable A whose value is either 0 or 1. When we perform OR operation with 0, the result will be the same as the input variable. So, if the variable value is 1, then the result will be 1, and if the variable value is 0, then the result will be 0. Diagrammatically, this rule can be defined as:

## What is the rule for ANDed with 0?

When we perform the AND operation with 0, the result will always be 0. This rule states that an input variable ANDed with 0 is equal to 0 always. Diagrammatically, this rule can be defined as:

## What is the addition operation of Boolean algebra?

The addition operation of Boolean algebra is similar to the OR operation. In digital circuits, the OR operation is used to calculate the sum term, without using AND operation. A + B, A + B’, A + B + C’, and A’ + B + + D’ are some of the examples of ‘sum term’. The value of the sum term is true when one or more than one literals are true and false when all the literals are false.

## What is the rule for ORed with its complement?

This rule states that a variable ORed with its complement is equal to 1 always. Diagrammatically, this rule can be defined as:

## What is the law of factoring?

According to this law, if we perform the OR operation of two or more variables and then perform the AND operation of the result with a single variable, then the result will be similar to performing the AND operation of that single variable with each two or more variable and then perform the OR operation of that product. This law explains the process of factoring.

## What is associative law?

This law states that the operation can be performed in any order when the variables priority is same. As ‘*’ and ‘/’ have same priority. In the below diagram, the associative law is applied to the 2-input OR gate.

## What are the rules of boolean algebra?

These rules plays an important role in simplifying boolean expressions. 1. A+0=A. 7.

## What are the operations of boolean algebra?

The important operations performed in boolean algebra are – conjunction (∧), disjunction (∨) and negation (¬). Hence, this algebra is far way different from elementary algebra where the values of variables are numerical and arithmetic operations like addition, subtraction is been performed on them.

## What is a boolean expression?

Boolean Expression. A logical statement that results in a boolean value, either be True or False, is a boolean expression. Sometimes, synonyms are used to express the statement such as ‘Yes’ for ‘True’ and ‘No’ for ‘False’. Also, 1 and 0 are used for digital circuits for True and False, respectively. Boolean expressions are the statements that use …

## How many types of Boolean algebra are there?

There are six types of Boolean algebra laws. They are:

## What is binary operation?

Any binary operation which satisfies the following expression is referred to as a commutative operation. Commutative law states that changing the sequence of the variables does not have any effect on the output of a logic circuit.

## How to convert a boolean equation into a truth table?

It is possible to convert the boolean equation into a truth table. The number of rows in the truth table should be equal to 2n, where “n” is the number of variables in the equation. For example, if a boolean equation consists of 3 variables, then the number of rows in the truth table is 8. (i .e.,) 23 = 8.

## Which branch of algebra deals with logical operations and binary variables?

Boolean Algebra: Boolean algebra is the branch of algebra that deals with logical operations and binary variables.

## What is binary algebra?

It is used to analyze and simplify digital circuits or digital gates. It is also called Binary Algebra or logical Algebra. It has been fundamental in the development of digital electronics and is provided for in all modern programming languages. It is also used in set theory and statistics.
