lesson 8

Question 1

commutative property of addition

Answer 1

if the order of the addends has changed, the sum says the same.

Question 2

commutative property of multiplication

Answer 2

if the order of the factor has changed, the product stays the same.

Question 3

associative property of addition

Answer 3

The way that the addends are grouped does not change the sum.

Question 4

associative property of multiplication

Answer 4

The way that the factors are grouped does not change the product.

Question 5

distributive property

Answer 5

Multiplying a sum by a number equals multiplying each addend by the number and adding the products.

Question 6

commutative

Answer 6

The commutative property means we can switch the order of things without changing the outcome.

Question 7

associative

Answer 7

The associative property means you can combine things in any order without changing the result. The associative property applies only to addition and multiplication.

Question 8

distributive

Answer 8

The distributive property means, for example, that you can not only combine the price of two items and then double this total if you want twice as many, but you could also double the price of each item first and then find the total. The price totals will be the same in both instances.
