Answers
Answer:
Changing the order of factors does not change their product.
Example:
a x b = b x a
4 x 20 = 20 x 4
Associative Property
Changing the grouping of factors does not change their product.
Example:
a x (b x c) = (a x b) x c
4 x (5 x 8) = (4 x 5) x 8
Identity Property
The product of any number and 1 is that number.
Example:
z x 1 = z and 1 x z = z
35 x 1 = 35 and 1 x 35 = 35
Zero Property
The product of any number and 0 is 0.
Example:
r x 0 = 0 and 0 x r = 0
12 x 0 = 0 and 0 x 12 = 0
Distributive Property
The product of a factor and a sum (or difference) equals the sum (or difference) of the product.
Example:
a x (b + c) = (a x b) + (a x c)
8 x (20 + 4) = (8 x 20) + (8 x 4)
TIP
Use the Distributive Property to make problems easier to solve:
(5 x 6) + (5 x 4) =
5 x (6 + 4) =
5 x 10 = 50
