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.

### 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.

### Commutative property of multiplication 3*7*2=

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

### 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.

### What is the parts of multiplication?

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!

### 1/3 x 2/5 =?

> 1/3 x 2/5 = ? Multiplication and division are "commutative" operations. So, (1 x 2) / (3 x 5) is equivalent. Simplify to get: (2) / (15)

### 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 )

a+0 = a where 0 is the additive identity
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
