associative property of real number

associative property of real number division

Associative property is explained as, more as two numbers are added (+) or multiplied(x), give the result remains as same, For example we have three real numbers a, b. c 

a +(b+c) = a +(b+c)  condition one

a ×(b×c) = a ×(b×c)  condition two

All numbers natural:

N ={1,2,3,4………………∞(…:mean all natural numbers without undefined

whole number:

W= {0,1,2,3,4,5,6………….∞(

set of integer: Z=)∞……..-6,-5,-4,-3,-2,-1,0,+1,+2,+3,+4,+5,+6……..∞(

Rational number :

Q={-1….-.5…..   0…1.5….1…1.5…..2….}

Irrational number Q’ ={all numbers which contain non-terminating and non-recurring decimal or numbering result is called irrational number}

Real number R = {set of all number N+W+Z+Q+Q’  called real number set}

We will discuss the associative property of real number addition, multiplication, negation and division.

associative property of real number
Associative property of real number negative not hold

Any number a, b, c we check these properties verify or not:

(1) associative property of addition

(2) associative property of multiplication

(3) associative property of subtraction

(4) associative property of division

associative property mean number objects and thing in the world we verify that

(1) associative property of addition:

associative property of real number

(a+b)+c= a+(b+c) …………………….. a

we take a numeric number 4, 6, 9 and apply on association

(4+6)+9= 4+(6+9)

10+9= 4+15

19=19

these number are verified associative property of real number.

Hence, addition of associative property verify

(2) associative property of multiplication:

now we take any three real numeric 1, 1/2, 2/4and check multiplication on associative property

(a+b)+c= a+(b+c)

(1+1/2)+2/4= 1+(1/2+2/4) by algebraic operation

3/2+1/2= 1+1

2  =  2

or

1   =   1

hence, verify association on these numbers

therefore, associative property is verifying the multiplication

(3) associative property of negation:

we take a three real number a=5, b= 6, c=7

associative property of negation on any number

a-(b-c)=(a-b)-c……….(a)

putting the value of a, b, c in association property “a”

5-(6-7)=(5-6)-7

5+1= -1-7

6= -6 this is not equal

association property of negative value of real number not hold

(4) associative property of division

associative property of real number division
Associative property of real number division, not hold

we take any three real number a= 2, b= 8,c=12

(a÷b)÷c= a÷(b÷c)……….(B)

putting the value of real number

(2÷8)÷12= 2÷(8÷12)

1/4÷12 =2÷2/3

by algebraic rule apply

1/4×1/12 =2×1/12

1/48 = 1/6………..not equal

hence, the property of association of division is not applicable
