## Arithmetic properties – Commutative, associative, distributive

Multiplication and addition are distinguished by unique mathematical features that distinguish them from one another. They are the commutative, associative, distributive, identity, and inverse properties, which are listed in no particular sequence.

## Commutative property

A commutative action is one in which altering the order of the operands has no effect on the outcome of the operation. This feature of addition is known as the commutative property, which indicates that the order in which the numbers are added is irrelevant. It follows from this that if you add 2 plus 1 to get 3, you can likewise add 1 plus 2 to obtain 3. In other words, the order in which the addends are placed does not affect the outcome; the results remain the same. Multiplication shares this trait, with the outcome being unaffected by a change in their relative positions among the components.

## Associative property

Because the order in which the operations are conducted does not matter in an expression having two or more occurrences of only addition or just multiplication, the order in which they are executed does not matter as long as the sequence of the operands does not vary. The term for this is the associative property. In other words, altering the parenthesis in such an expression will have no effect on the value of the expression. For example, group and add the following numbers:\$1 + 5 + 9 + 5 =?\$ Simplest solution is to utilize the commutative property to flip their positions, and then the associative property to combine pairings such as \$1\$ & \$9\$, as well as \$5\$ & \$5\$, because these sums total \$10\$, and the ultimate result is \$20\$.

## Distributive property

The distributive property combines the operations of addition and multiplication together. If a number multiplies a sum enclosed in parentheses, the parenthesis can be eliminated if we multiply each phrase within the parenthesis with the same number (which is not always the case). It makes no difference how many terms are contained within the brackets; this will always be legitimate. This attribute is typically used when an unknown is included in an addition operation, and it allows us to distinguish between the unknowns.

## Identity element

The identity element, also known as the neutral element, is an element that when mixed with other components keeps them unaltered. The identity element for addition is zero, whereas the identity element for multiplication is one.

## Inverse element

The multiplicative inverseor reciprocal for a number \$x\$ is symbolized by the symbol \$frac\$. It is a number that, when multiplied by \$x\$, provides the multiplicative identity, or 1. The multiplicative inverse of a fraction \$frac\$ is the fraction \$frac\$ itself. In the case of a number \$x\$, the additive inverse is the number that, when multiplied by \$x\$, produces zero. Additionally, this number is referred to as the opposite(number), the sign change, and the negation. When applied to a real number, it changes the sign of the number: the opposite of a positive number is negative, and the opposite of a negative number is positive, and so on.

Zero is the additive inverse of its own value, and vice versa. Example: The reciprocal of the number 5 is \$frac\$, and the oppostie number to the number 5 is -5.

### What is the difference between commutative and associative property?

The multiplicative inverseor reciprocal for a number \$x\$, indicated by the symbol \$frac\$, is a number that, when multiplied by \$x\$, provides the multiplicative identity, which is 1. the \$frac\$-th power of two is equal to the dollar sign \$frac\$-th power of two. x\$ is an integer and the additive inverse of that integer is the number that, when added to \$x\$, returns 0. This number is also referred to as the opposite(number), the sign change, and the negation of another number. Real numbers have their signs reversed: a positive number’s opposite is a negative number, and the opposite of a negative number’s positive number is a negative number.

Example: The reciprocal of the number 5 is \$frac\$, and the oppostie number of the number 5 is -5.

###### Commutative property vs Associative property

You can modify the order in which you add or multiply the numbers and yet receive the same answer if they have the commutative property or commutative law. To illustrate this point, consider the commutative feature of addition: if you have 2 + 4, you can easily modify it to 4 + 2 and still get the same result (6). The commutative property of multiplication has the same effect as the preceding one. If you have a 2 x 4 matrix, you may alter it to a 4 x 2 matrix and have the same result (8). When compared to associative property or associative law, there is a distinction in that it involves more than two integers.

1. The crucial thing to remember is that it’s only addition or only multiplication, respectively.
2. Because addition has the feature of associativity, you can add the integers in any sequence.
3. This is true whether you add 2 to 3 to 1 to 5 to 6 or if you add the 2 and 3 together to get 5 and then add the 1, 5 and 6 together to get 12, and the 5 and 12 together to get 17.
4. It is the same associative feature for addition and multiplication.
5. So, for example, in the issue 2/3/5/6, you may multiply 2/3 to obtain 6, then 5/6 to get 30, and the final result is 180 by multiplying the final result by the first two factors of the problem (2/3/5/6).

## What are the Properties of Operations in Arithmetic?

Arithmetic has perhaps had the longest history of any subject throughout this period. It is a technique of computation that has been in use since ancient times for routine calculations such as measurements, labeling, and all other types of day-to-day calculations that require precise numbers to be obtained. The name “arithmos” comes from the Greek word “arithmos,” which literally translates as “numbers.” Arithmetic is a fundamental branch of mathematics that is concerned with the study of numbers and the properties of traditional operations such as addition, subtraction, multiplication, and division.

Arithmetic, in addition to the classic operations of addition, subtraction, multiplication, and division, also includes complex computations such as percentage, logarithm, exponentiation, and square roots, among other things.

Arithmetic is a discipline of mathematics that is concerned with the representation of numbers and the customary operations on them.

### Basic Operations of Arithmetic

According to the statement, there are four fundamental operations in arithmetic that are utilized to do calculations: (+) is used to indicate an addition. Simple description of addition will be that it is an operation that combines two or more values or numbers to form a single value or value set. Summation is the term used to describe the process of adding n numbers of values together. In mathematics, the number zero is referred to be the identity element of addition since adding zero to every value produces the same result.

• 0 plus 11 equals 11.
• An identity element with value zero will be produced as a result of combining inverse elements.
• Subtraction(-) In mathematics, subtraction is the arithmetic operation that is used to compute the difference between two different numbers (i.e.
• It is possible to have a positive difference in the condition where the minuend is greater than the subtrahend.
• 6 minus 2 equals 4.
• 2 – 6 equals -4 Multiplication(×) Known as multiplicand and multiplier, they are the two values that are involved in the action of multiplication.
• It is possible to describe the product of two values presumably named p and q in either the p.q or the p q form.
• It is the inverse of the operation of multiplication.
• 15 divided by 3 equals 5.

### Properties of Arithmetic

The following are the primary characteristics of arithmetic:

• Commutative property
• Associative property
• Distributive property
• Identity element property
• Inverse element
• Commutative property

The property of commutativity In other words, it doesn’t matter what order the numbers are arranged in; the addition operation on them will provide the same result even if the numbers are swapped or reversed in their position. Alternatively, we might state that the order in which the numbers are added can be modified, but the outcomes will remain the same. In addition to addition and multiplication, this concept is also applicable to subtraction and division. x plus y equals y plus x For example, if we multiply 3 by 2 or 2 by 3, the outcomes will be the same.

• It makes no difference in whatever order the operations of addition and multiplication are executed as long as the sequence of the integers is not altered during the process.
• To put it another way, rearranging the numbers in such a way that their values remain unchanged.
• z equals x.
• Property with a Distributive Effect It is possible to simplify the multiplication of a number by a sum or difference because of this characteristic.
• x y (y + z) = x y + x z, and x y (y – z) = x y – x z.
• For example, simplify 4 x (5 + 6)= 4 x 5 + 4 x 6= 20 + 24= 44 by dividing by 4.
• Property of the Identity Element When coupled with other components, this is an element that does not modify the other elements in any way.
• Addition is represented by x + 0 = x, while division is represented by x.0 = 0.
• The Reverse Element It is symbolized by the symbol 1/a.
• The multiplicative inverse of a fraction is represented by the symbol a/b.
• This number is also referred to as theadditive inverseor opposite (number), sign change, and negation, among other things.

Alternatively, we may argue that given a real number, it reverses its sign from positive to negative and from negative to positive, and vice versa. Zero is the additive inverse of itself. As an illustration, the reciprocal of 6 is 1/6 and the additive inverse of 6 is -6.

### Sample Questions

Question 1: The total of two integers equals 100, and the difference between them equals thirty. Look up the numbers. Solution: Let the integers a and b serve as examples. As a result of the current circumstance, a + b = 100.(i) and a – b = 30. ……………… (ii) To formulate equation I we may use the expression a = 100-b. When we insert the value of an in equation (ii), we obtain the following results:100 – b = 30100 – 2b = 302B =100 – 302B =100 – 302B = 70B = 70/2B = 35anda = 100 – 35a= 65a= 100 – 35a= 65a= 65a= 65a= 65a= 65a As a result, the two numbers are 65 and 35 respectively.

## Properties of Arithmetic Mean

When it comes to measures of central tendency, the arithmetic mean is one such measure that may be defined as the sum of all observations divided by the total number of observations. Let us now consider the characteristics of the arithmetic mean. Observation 1: If all of the observations assumed by a variable are constants, such as “k,” then the arithmetic mean is also equal to “k.” For example, if the mean height of a group of ten students is 170 cm, the mean height of the group is, of course, 170 centimeters as well.

1. This means that for unclassified data, (x – x)=0.
2. For example, if a variable “x” is assumed to have five observations, such as 10, 20, 30, 40, and 50, thenx=30 is true.
3. The observations’ deviations from the mean (x -x) are 0, 10, and 20.
4. This means that y = a + bx.

Calculate the arithmetic mean of “y” using the formula: (-7 – 2×15) / 3Arithmetic mean of “y” using the formula: (-7 – 30) / 3Arithmetic mean of “y” using the formula: (-37 – 30) / 3Arithmetic mean of “y” using the formula: (-7 – 12) Property 4: If there are two groups comprising n 1 and n2 observations, and x1 and x 2 are the respective arithmetic means, then the combined arithmetic mean is provided byx=(n1x1+ n2x2) / (n 1+ n 2), and the combined arithmetic mean is given byx=(n1x1+ n2x2) This property might be expanded to include more than two groups, and we could express it asx=nx / n to represent this.

In this case, n x=n 1 x 1+ n 2 x 2+.n=n 1+ n 2+.n=n 1+ n 2+.

## Some Other Properties of Arithmetic Mean

1) It has a very strict definition. 2)It is based on the results of all of the observations. 3)It is simple to grasp the meaning of. 4)It is straightforward to compute. 5) It is the least impacted by the existence of extreme observations, according to the results. 6) It may be subjected to mathematical treatment or has mathematical qualities. Because of the characteristics listed above, the “Arithmetic mean” is the best measure of central tendency. However, there are certain disadvantages to using the arithmetic mean.

• 2) It is not recommended to use the arithmetic mean to open a classification.

## What is Number Properties? – Definition, Facts and Examples

The four most important number qualities are as follows:

• Commutative property, associative property, identity property, and distributive property are all examples of properties.

## Commutative property:

Because of this trait, the numbers on which we conduct the operation can be relocated or swapped without making any impact to the outcome of our calculation. Although this principle holds true for addition and multiplication, it does not hold true for subtraction and division. The commutative property of addition is demonstrated in this example. 3 plus 5 equals 5 plus 3 equals 8 In other words, for any two real numbers a and b, the commutative property of addition for any two real numbers is as follows:a + b = b + a.

Because of this, the commutative property of multiplication for any two real numbers a and b is_axb=bxa, and for any two real numbers The commutative feature also allows us to declare that the numbers can be added or multiplied with each other in any sequence without altering the answer.

## Associative Property:

The associative property takes its name from the word “Associate,” and it refers to the grouping of numbers that occurs when two or more numbers are combined. This characteristic asserts that when three or more numbers are added (or multiplied), the sum (or product) remains the same regardless of how the addends are grouped together in the addition or multiplication process (or multiplicands). Take the following example: (3 + 4) + 5 = (4 + 5) + 3 (four times seven multiplied by five) = (4 times five multiplied by seven = 140

## Identity Property:

 Additive identity Multiplicative identity Additive identity is a number, which when added to any number, gives the sum as the number itself.This means, the additive identity is “0” as adding 0 to any number, gives the sum as the number itself. Multiplicative identity is a number, which when multiplied by any number, gives the product as the number itself.This means, the multiplicative identity is “1” as multiplying any number by 1, gives the product as the number itself.

## Distributive Property:

Using the distributive property, we can make the multiplication of a number by a sum or difference more simpler. As the name implies, it is responsible for disseminating the phrase. As an illustration, consider the expression:a x (b + c). We may simplify the equation by referring to its distributive property:

 Example of distributive property using addition Example of distributive property using subtraction
• Alternatively, the additive identity property is referred to as the zero property of addition. Because of the term commutes, which means to move around, the commutative property was given its name.

## Basic Number Properties: Associative, Commutative, and Distributive

In mathematics, there are three fundamental features of numbers, and your textbook will most likely contain only a brief section on these properties, sometime around the beginning of the course, after which you will almost certainly never see them again (until the beginning of the next course). To my knowledge, this is a hangover from the “New Math” debacle of the 1960s. While the concept will become more essential in matrix algebra and calculus (and will become incredibly important in advanced mathematics a couple of years after calculus), it isn’t particularly important right now in the context of the course.

What’s the harm in trying?

Imagine dealing with a system in which, for example, the value ofa did not in fact equal the value ofb; or where the value ofa did not in fact equal the value of(a b)c; you have never dealt with such a system.

For the time being, don’t be concerned with their “relevance”; instead, focus on making sure you can maintain the attributes straight so that you can pass the next exam.

## Distributive Property

If you recall that “multiplication distributes over addition,” the Distributive Property is simple to memorize. This property is written as “a (b+c) =ab+ac” in formal notation. The numerical equivalent of this is 2(3 + 4), which is equal to 2 3 + 4 in two-digit format. The Distributive Property is utilized whenever someone refers to it in a problem; each time a computation relies on multiplication through parentheses (or factoring things out), the Distributive Property is employed whenever someone refers to it in a problem.

#### Why is the following true?2(x+y) = 2 x+ 2 y

Because they dispersed through the parenthesis, the Distributive Property determines that this is true.

#### Use the Distributive Property to rearrange:4 x– 8

The Distributive Property either removes anything by putting it in parenthesis or it removes something by factoring it out. Because there aren’t any parenthesis to put in, you must factor out of the equation. Then the solution is as follows: In accordance with the Distributive Property, 4 x– 8 = 4(x– 2). “But hold on a sec!” “How come the Distributive Property states multiplication distributes over addition, but not over subtraction?” I hear you exclaim. “What gives?” You make an excellent point.

You can think of the contents of the parenthesis as either the subtraction of a positive number (“x– 2 “) or the addition of a negative number (“x+ (–2) “) depending on your perspective.

The other two attributes are available in two different variations: one for addition and one for multiplication, respectively.

(Yes, the Distributive Property pertains to both addition and multiplication as well, but it refers to both operations inside a single rule, rather than both operations within two different rules.)

## Associative Property

The term “associative” is derived from the words “associate” and “group,” and the Associative Property is the rule that relates to grouping in a mathematical context. In addition, the rule is “a+ (b+c) = (a+b) +c”; in numbers, this implies that 2 + (3 + 4) = (2 + 3) + 4; in words, this means 2 + (3 + 4) = (2 + 3) + 4. Multiplication is done according to the formula “a (bc) = (ab) c,” which indicates that 2(34) Equals (23)4 in numbers. It is their intention that you regroup things wherever they refer to the Associative Property, and that you state that the calculation relies on the regrouping of things whenever you declare that the computation makes use of the Associative Property.

#### Rearrange, using the Associative Property:2(3 x)

#### Why is it true that2(3 x) = (2×3) x?

Because all they did was reorganize things, the Associative Property determines that this is correct.

#### Why is it true that3(4 x) = (4 x)(3)?

## Properties of Arithmetic Mean

It is necessary to adhere to the characteristics of the arithmetic mean in order to answer various sorts of questions on average. Here, we will learn about all of the features of the arithmetic mean, as well as how to prove it using a step-by-step explanation. What exactly are the characteristics of arithmetic mean? The qualities are detailed in further detail below, with appropriate illustrations. Suppose x is the arithmetic mean of n observations x 1, x 2, x 3,., and so on; then (x 1- ) + (x 2- ) + (x 3- ) + (x 4- ) + (x n- ) = 0.

## Properties of Arithmetic Progression

We will cover some of the features of Arithmetic Progression, which we will commonly utilize in solving various sorts of issues involving arithmetical progression in the next sections of the course. A property of an Arithmetic Progression (A. P.) is that if a constant number is added to or removed from each term of an A. P., the resulting terms of a series are also in the A. P. and have the same common difference (C.D.). Proof: (i)Assume that there is an Arithmetic Progression with the common difference d.

1. Allow k to be a fixed constant amount once more.
2. I is now multiplied by k.
3. (iii) is a(_ ), and so on until the end of the A.P.
4. The new sequence is b(_ ), b(_ ), b(_ ), b(_ ), b(_ ), b(_ ), b(_ ), b(_ ), b(_ ), b(_ ).
5. Let’s have a look at the following explanation to acquire a better understanding of property.
6. Following that, the Arithmetic Progression is used.
7. By including a constant quantity such as: Adding a constant number k to each term of theArithmetic Progression a, a + d, a + 2d, a + 3d, a + 4d,.

In the preceding sequence I the first term is (a + k), and the second term is (b + k).

As a result, the words in the preceding sequence I combine to produce an Arithmetic Progression (AP).

If we subtract a constant number, say k, from each phrase of theArithmetic Progression a, a + d, a + 2d, a + 3d, a + 4d, we obtain the following:a – k,a + + d,.a + 2d,.a + 3d,.a + 4d.

There is a common difference between the aforementioned sequence (ii) and the sequence I (a + d-k) – (a + d-k) = d.

Because of this, it is possible to subtract a constant number from each term of an Arithmetic Progression and have the resultant terms be in the same Arithmetic Progression as the original terms with the same common difference.

Theorem: Assume that a(_ ) is an Arithmetic Progression with the common difference d, then a(_ ) is an Arithmetic Progression with the common difference d, and so on.

The sequence b(_ ) is obtained by multiplying each term of the specified A.P.

This is denoted by the symbol.

P.

dk.

Assume that ‘a’ is the first term and ‘d’ is the common difference of an Arithmetic Progression and that ‘a’ is the first term.

On multiplying a constant number:If a non-zero constant quantity k ( 0) is multiplied by each term of theArithmetic Progression, we obtain the following results: (iii)The first word in the preceding sequence (iii) is the letter ak.

As a result, the words in the preceding sequence (iii) form an Arithmetic Progression, as shown in the diagram.

2.

(iv) The first term in the above sequence (iv) is (frac).

Because of this, when an integer constant number is divided by each term of an Arithmetic Progression, the resultant terms are also included in the Arithmetic Progression as a result of the division.

For the sake of argument, let us suppose that ‘a’ is the first term, ‘d’ represents the common difference, ‘l’ represents the last term, and ‘n’ represents the number of terms in an A-P formula (n is finite).

4d is the fourth term from the end of the equation.

In this case, the rth word from the beginning is equal to a + (r – 1)d.

In Arithmetic Progression, three numbers are considered to be in progress if and only if the product of two numbers is equal to the sum of the two numbers plus the sum of the three numbers.

As a result, the common difference is equal to y – x and, once more, the common difference is equal to z-y.

In the alternative, consider three integers x, y, and z such that 2y = x + z.

There are three variables in Arithmetic Progression.

V: A series is an Arithmetic Progression if and only if its nth term is a linear expression in the number n, i.e., a(_ ) = A(_ ) + B, with A and B being two constant numbers.

a series is an Arithmetic Progression if and only if the total of its first n terms is of the form An(n) + Bn, where A and B are two constant variables that are independent of the number of terms in the sequence.

if the terms in a series are taken at regular intervals from an Arithmetic Progression, then the sequence is considered to be an Arithmetic Progression.

In the case of an Arithmetic Progression with three consecutive terms x, y, and z, then 2y = x + z is the property VIII. Arithmetic Progression is a term used to describe the progression of numbers.

## WRKDEV100- Properties of Real Numbers

Do you recall the first time you used a cell phone? For example, do you remember your first GPS (Global Positioning System) or your first video gaming console? Your encounter with new technology, whether it was with the Droid in your pocket or the Nintendo with those heavy plastic cartridges that you had to blow dust out of in order for the game to run, was most likely comparable to your experience with old technology. You took the time to learn everything you could about how your new device operated.

Mathematical reasoning is no exception.

In this lesson, you will learn about some of the features of real numbers and how they may be used to solve problems.

You should be able to do the following by the conclusion of this lesson:

## Presentation

Take a closer look at each of the buildings.

### TheClosure Properties

Addition, subtraction, and multiplication all result in the closure of real numbers. Thus, ifaandbare real numbers, thena+bis a unique real number, andabis a unique real number are both valid options, respectively. For instance, the numbers 3 and 11 are actual numbers. 3 plus 11 equals 14, and 3 minus 11 equals 33. Take note that the numbers 14 and 33 are both genuine numbers. A realnumber is produced whenever two real numbers are added together, subtracted from each other, or multiplied together.

Here are a few illustrations.

2 Natural numbers do not have a closed form when subtracted.

(0 is not a natural number since 8 + 8 = 0, and 0 is not an even number.) Watch the following video for a more in-depth discussion of the Closure Property, as well as several instances.

### The Commutative Properties

It is known as the commutative property, and it states that two integers can be added or multiplied in any order without changing the outcome. Real numbers are represented by the letters a and b.

 Commutative Property of Addition Commutative Property of Multiplication a + b = b + a a⋅b = b⋅a
 Commutative Properties: Examples 3 + 4 = 4 + 3 Both equal 7 5 + 7 = 7 + 5 Both represent the same sum 4 ⋅ 8 = 8 ⋅ 4 Both equal 32 y 7 = 7 y Both represent the same product 5 (3+1) = (3+1) 5 Both represent the same product (9 + 4) (5 + 2) = (5 + 2) (9 + 4) Both represent the same product

### The Distributive Properties

When you were initially exposed to multiplication, you most certainly realized that it was originally intended to serve as a description for the process of repeated addition. Considerthis: 4 plus 4 plus 4 equals 3 and a half. Take note of the fact that there are three 4s; that is, the number 4 appears three times. As a result, 3 times 4 equals 12. Algebrais generalized arithmetic, and you are now in a position to develop a significant generalization of your own. a+a+a+ +a (aappearsntimes) is formed when thenumberais added repeatedly, meaningntimes.

Example 1:x+x+x+x can be represented as 4 x since xhas been added four times in a row.

r+r= 2 r is a mathematical formula.

See the description below for further information. 4(a+b) should be rewritten. STEP1: You begin by interpreting 4(a+b) as a multiplication problem: (a+b) multiplied by four equals four times the quantity.

• This tells you to write the following:
• 4 (a+b) = (a+b) + (a+b)+ (a+b) + (a+b) =a+b+ a+b+ a+b+ a+b+ a+b+ a+b+ a+b+ a+b+ a+b+ a+b+ a+b+ a+b+ a+b+

In this step, you will utilize the commutative property of addition to group all of the a′s and all of the b′s together.

• This instructs you to write: 4(a+b) =a+a+a+a+a+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b 4 a ′s plus 4 b ′s

STEP 3:At this point, you describe repeated addition by referring to it as multiplication.

• It is your responsibility to allocate the 4 across the money to bothaandb.

It is theDistributive Property that we are talking about.

 The Distributive Property a(b+c) =a⋅b+a⋅c (b+c)a=b⋅a+c⋅a

The following may also be written because of the commutative property and habit of putting the variables in alphabetical order: b+c=a+c,so(b+c) a=a+ctoo, and b=a+c also. When you are unable or do not prefer to conduct operations within parenthesis, thedistributive property can be really handy. Examples Rewrite each of the following quantities using the distributive property to make them easier to understand. 2(5 + 7) = 6 (x+ 3) = (z+ 5)y= 2(5 + 7) = 6 (x+ 3) = (z+ 5)y= 2(5 + 7) = 6 (x+ 3) = (z+ 5)y= For a more in-depth discussion of the Distributive Property, please see the videos included below.

## Practice Exercise: Distributive Properties

Make use of the distributive property to rewrite each of the following amounts such that they do not include any parenthesis. When you use the distributive property to conduct operations on an expression, this is referred to as “expanding the expression.” Practice Exercise 3 (2 + 1) (x+ 6) 7 4 (a+y) (9 + 2)a a(x+ 5) 1 (x+y) (x+y) (x+y) (x+y) (x+y) (x+y) Answers may be found here.

6. X+y 4 a+ 4 y 4 a+ 4 y 4 a+ 4 y 4 a+ 4 y 4 a+ 4 y 4 a+ 4 y 4 a+ 4 y 4 a+ 4 y

### The Identity Properties

Additive Identity is a term used to describe a person who has an additional characteristic. In mathematics, the number zero is referred to as the additive identity because when it is added to any real number, it maintains the identity of the original number. Zero is the only identity that is additive. As an illustration: 6 plus 0 equals 6. Multiplicative Identity is a term used to describe a person who has more than one identity. It is termed the multiplicative identity because when the number 1 is multiplied by any real number, it retains the identity of that number, thus earning the name.

As an illustration, the number 6 divided by one equals six.

 Additive Identity Property Multiplicative Identity Property Ifais a real number, thena+ 0 =aand 0 +a=a Ifais a real number, thena⋅ 1 =aand 1 ⋅a=a

Check out the following Khan Academy videos for an in-depth explanation of the Identity Property as well as practical examples.

### The Inverse Properties

Example Six plus one equals one when multiplied together, i.e., six plus one equals one.

The numbers 6 and are the multiplicative inverses of one another in the number system. The multiplicative inverse of what is the following: The following are the inverseproperties of the function. The Inverse Properties of a System

Ifais any real number, then there is aunique real number − a, such thata+ (− a) = 0 and − a+a= 0
• The integers a and an are referred to as additive inverses of one another.
Ifais any nonzero real number, then there is a unique real numbersuch thata⋅= 1 and⋅a= 1
• In mathematics, the numbersa and are referred to as multiplicative inverses of one another.
