Can you give an example of Distributive Property of Multiplication over Addition?
8*37 = 8*(30+7) = 8*30 + 8*7 [that is using the distributive property] = 240 + 56 = 296
Give an example of the commutative property of addition?
3+5 = 8 = 5+3 commutative is just switching the numbers around and the answers stay the same.
Give an example showing that the commutative property does not hold for division of whole numbers?
Here is an example: 4/2 = 2 Commutative property is when you can move numbers around in a problem, and it wouldn't change. This is why it doesn't work in division 2/4 = 1/2 The commutative property applies to only addition and multiplication. It does not apply to division or subtraction. More examples: Addition: 2 + 3 = 3 + 2 = 5 Subtraction: 2 - 3 = -1, 3 - 2 = 1 Division: (see above) Multiplication: 3(5) = 5(3) = 15
Can you Give an example of a problem involving multiplication of fractions that can be made easier by using the associative?
Here is an example:27 x 25 x 40 If you calculate the RIGHT multiplication first, you can quickly find the product, 1000 - since 25 x 4 = 100, and then you attach one more zero. Calculating 27 x 1000 is quite trivial.
What is Result of an addition?
The result is called the sum of the two numbers. The operation of addition is commutative. This means that the addition of two numbers will give the same sum regardless of the order in which the numbers are added.
