You need the associative and commutative properties, but not the distributive property. n*4n*9 =n*(4n*9) (associative) = n*(9*4n) (commutative) = n*(36n) (associative) = 36n*n commutative = 36*n^2

The associative property states, no matter how you order three or more integers being added, they will always equal the same solution. For example, A + (B + C) = (A +B) + C * * * * * The equation is correct but the description is not. When you say "no matter how you order three or more integers" you are implying that A + B + C = A + C + B and that need not be true. Associativity refers to the order in which the summation is carried out. That does not matter.

no

The distributive property of multiplication over addition and the identity property of multiplication. RS + RS = 1*RS + 1*RS (using identity property) = (1 + 1)*RS (using distributive property) = 2*RS

In general, the associative property cannot be used for this purpose. The volume of a prism is the area of cross section multiplied by the length, and except in the case of a rectangular prism, there is no scope for using the associative property.

I am guessing your problem is to compute 5 times 2 times 13. In this case, the property you are using the associative property.

The Associative Law of Addition says that changing the grouping of numbers that are added together does not change their sum. This law is sometimes called the Grouping Property. Examples: x + (y + z) = (x + y) + z. Here is an example using numbers where x = 5, y = 1, and z = 7.

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).

4*25*27 = (4*25)*27 = 100*27 = 2700

no

So you don't have to use mental math or fingers

The commutative property of addition applies to all real and complex numbers. It has nothing whatsoever to do with the form in which the number is represented: decimal, binary, etc.

The distributive property of multiplication over addition and the identity property of multiplication. RS + RS = 1*RS + 1*RS (using identity property) = (1 + 1)*RS (using distributive property) = 2*RS
