Commutativity and associativity.
Commutative property of addition :)
That is the commutative property of either multiplication or addition.
It is the commutative property of addition.
The Commutative property applies to both addition and multiplication. It states that the answer is independent of the order of the expression. In other words, it does not matter in which order you put the numbers in the problem.For example, in addition:3 + 5 = 8is the same as:5 + 3 = 8It does not matter in which order you place the numbers, the answer is still the same.Similarly, for multiplication:9 x 7 = 63is the same as:7 x 9 = 63
commutative and associative. If the sentence has parentheses then it is associative.

The parentheses can be used to change the order of terms in an expression. This is because the properties inside the parentheses are done before those outside of them.
That is the commutative property of either multiplication or addition.
In the expression 3(4+5)which property allows you to distribute the 3to both the 4and 5
22 + 14 + 8 = 14 + 22 + 8 [the commutative property of addition allows you to change the order of the operands] = 14 + (22 + 8) [by the associative property, the order in which the additions are performed does not matter] = 14 + 30 = 44
When elements are grouped without change of order, as: (a+b)+c=a+(b+c)

Changing the order of addends does not change their sum. In symbolic form, a + b =b + a. Subtraction is not commutative .
According to the commutative property of addition, the order of the addends does not affect the result. Thus, A + B = B + A
The use of parentheses allows you to control, or change, the regular order of operations. For example, if you have the expression 4 + 2 * 3, under the normal order of operations, you would perform the multiplication before the addition. To perform the addition first, you just add parenthesis so the expression reads (4 + 2) * 3 instead.
