If there was a question it is not clear. I will show you what commutativity works. Whether that answers your lack of question remains to be seen.
Commutativity of multiplication (or the commutative property of multiplication) means that the order of the factors in a product does not affect the result. In other word, the order of factors is unimportant.
3*7+2 =7*3+2=23
2*7*3=2*3*7=7*2*3=7*3*2=3*2*7=3*7*2=42

How do you use the commutative property to mentally add 52+36+8+4?


In fact you will use the associative property and the commutative property.
52+36+8+4=52+8+36+4=(52+8)+(36+4)
36+4=40
52+8=60
60+40=100.

What does commutative property means ?


A mathematical operation ( lets call op, it can be addition or multiplication) such that
a (op) b= b(op) a
Examples:
if op is the addition then 3+5=5+3=8
if operation is multiplication then 3*5=5*3=15
If the result of an operation involving two numbers is the same regardless of which number is first or second, the operation is said to be commutative, or to verify (satisfy) the commutative property.
Examples of non commutative operations.
2/3 =0.666, but 3/2 =1,5. The two results are different and the division operation is NOT commutative.
Similarly, 2-3 =-1, but 3-2 =1. Again the subtraction is NOT commutative.
Other example: In the morning Shower then dress, or Dress then shower. Clearly the results are quite different.

What is commutative property


An operation is said to be commutative if the order of the operands does not change the result.
Let an operation be called O.
If aOb=bOa the operation is called commutative.
Addition and multiplication of real numbers are commutative
3+7=7+3
3*7=7*3
However division and subtraction are not commutative
3-7 is not = to 7-3
3/7 is not = to 7/3.
That is the gist of it.

What is the commutative property of addition??


Didn't anyone reply? It just means a+b is the same result as b+a. For example a/b is not commutative.

Use commutative property to find 5X4


Multiplication is commutative. That means that the order of the factors will not affect the product.
5x4=4x5=20.

I don't know what commutative property is


If this is Math, it means that the position of your numbers does not matter -- the result will still be the same.

Example:
1 + 3 is the same with 3 + 1. The answer for both will be 4.
5 x 2 is also the same with 2 x 5, having an answer of 10.

This only applies for addition and multiplication.

What is the parts of multiplication?


If you are asking about The Parts of a Multiplication Sentence, answers are:
5x2 = 10
The number 5 is the multiplicand The number 2 is the multiplier The answer, which is 10 is the product.
If in case you are looking for The Properties of Multiplication:
a. Commutative or order property b. Associative or grouping property c. Distributive property d. Identity element or property of one e. Zero property
Hope that helps!

Commutative Properties


    There are two Commutative Properties, which are as follow 1) Commutative Property of Addition :-According to it changing the order of addends does not change the sum. That is, a + b = b + a.
    2) Commutative Property of Multiplication:- According to it changing the order of factors does not change the product. That is, a × b = b × a.

              UNDERSTANDING MATH PROPERTIES OF REAL NUMBERS


              Hii,here is list of basic real numbers properties applying them you can solve the problems easily.


              Assuming a,b,c,d are real numbers:

              1)Commutative Property
              a) Property of Addition: a+b = b+a
              b)Property of Multiplication: ab = ba


              2)Associative Property
              a)Property of Addition: (a+b) + c = a + (b + c)
              b)Property of Multiplication: ( ab )c = a ( bc )


              3)Additive Identity:
              a+0 = a where 0 is the additive identity
              4)Additive Inverse:
              For real number a, there exists -a such that
              a+(-a) = 0
              5)Multiplicative Identity:
              For real number a,
              1 X a = a
              where 1 is the multiplicative identity
              6)Multiplicative Inverse:
              For real number X where a≠0, there exists 1/asuch that
              a X(1/a) = 1
              7)Zero Product Law:
              If ab = 0, then a=0 or b=0 or both a and b = 0.

              8)Distributive Properties:
              a)Left distributive law
              a (b + c ) = ab + ac
              b)Right distributive law
              (a + b) c = ac+ bc

              8y-4(5-6y)+20 distributive property


              Hello,
              You are talking of the distributivity of multiplication with respect to the addition or subtraction. The only term where you have multiplication and addition/subtraction is the one with parentheses because
              4(5-6y) = 4*(5-6y). * means multiply by

              Distributing the product consists in removing CORRECTLY the parentheses.
              I consider the term alone
              4*(5-6y) = 4*5 +4*(-6y)= 20 -4*6*y = 20 -24*y
              You put this result in a package and replace it where it was it the original expression.
              So
              8*y -(package) +20= Replace package
              8*y -(20-24*y)+20 = 8*y -20 -(-24y) + 20 Remember -*(-) = +
              8*y -20 +24*y +20= Remember -20+20 =0
              8*y -20 +20 +24*y= Addition is commutative
              8*y +24*y = 32*y
              Let y be an orange 8 oranges + 24 oranges =32 oranges.Coclusion
              8y-4(5-8y)+20 = 32y
