Yes. Multiplication of any real numbers has the associative property: (a x b) x c = a x (b x c)

The associative property of multiplication. For an example of the associative property, read on. 2 x 3 x 4= 2 x 3 x 4. Simple, huh?

This is an example of the commutative property of multiplication

Do the 2 x 50 first. Get 100. Multiply that by 14.

Answer: The associative property involves three numbers, not two. Of course, you can use one of the numbers more than once. For example, show, by calculation, that (2 x 2) x -2 = 2 x (2 x -2).

(2 x 3) x 4 = 2 x (3 x 4) Basically you switch the parentheses

No, multiplication is associative. 5 x (4 x 3) = 4 x (5 x 3) = 3 x (5 x 4) = 5 x 4 x 3 = 60

The commutative property holds that the results are the same no matter the order. Multiplication is commutative since a x b = b x a. The associative property holds that the results are the same no matter the grouping as long as the order stays the same. Multiplication is associative since (a x b) x c = a x (b x c)

The commutative property works for adding and multiplying e.g. 2+4=4+2 and 3x4=4x3. But it doesn't work for subtraction and division so 5-3≠3-5 and 6÷2≠2÷6 so subtraction and division could be considered as exceptions.

It means that if you change the grouping (parentheses) of a multiplication problem, you will still get the same answer. Ex. (3 x 2) x 4 = 24 and 3 x (2 x 4) = 24. You changed the location of the parentheses, but the product always remains 12.

Commutative means that the order can be changed without affecting the answer. For example, multiplication is commutative but division is not. 2 x 4 = 8 and 4 x 2 = 8 (commutative) 2 / 4 = 1/2 but 4 / 2 = 2 (not commutative) Associative means that the order that two operations is completed can be changed without affecting the answer. (2 x 4) x 3 = 2 x (4 x 3) - (associative)

You can indicate the multiplication with a multiplication sign. If your matrices are "A" and "B", the product is: A x B In other words, you are indicating the product, but not actually carrying out any multiplication. Anybody who understands about matrices should know what this refers to.

Yes. The Associative Property of Multiplication states that 3 x 4 = 4 x 3

no

40nX10m Since multiplication is commutative and associative you can rearrange this to be 40x10xmxn and get 400mn.

No. In general, if A and B are square matrices of the same size, A times B is not equal to B times A.Write down two random 2 x 2 matrices, multiply them together in both orders, and see what you get.

(3 x 5) x 7 = 3 x (5 x 7) Of course, the product will no longer be prime.

Suppose you were trying to multiply 17 x 5 x 2. The associative property states that (17 x 5) x 2 = 17 x (5 x 2) The second one is easier to do in your head.

The answer is 16 x 25, because no matter how it is written the answer will be the same. This rule also applies for addition as well as multiplication.

Commuting in algebra is often used for matrices. Say you have two matrices, A and B. These two matrices are commutative if A * B = B * A. This rule can also be used in regular binary operations(addition and multiplication). For example, if you have an X and Y. These two numbers would be commutative if X + Y = Y + X. The case is the same for X * Y = Y * X. There are operations like subtraction and division that are not commutative. These are referred to as noncommutative operations. Hope this helps!!
