Incorrect

The solution is 0.25(15) + 0.25(35). The order in which the products are added does not matter. This is an example of using the commutative property. Solution

This is the result of solving an equation to find a value(s) for the variable(s) which make the equation true. Product

This is the result after multiplying a set of numbers or algebraic expressions. Commutative Property

This property allows you to change the order of the terms when adding OR multiplying without changing the outcome. 1)

Correct

Solution: Sadie. Sadie has moved the parentheses from the (a + b) to the (b + c). She has correctly used the associative property. Associative Property

It is the property that allows you to regroup numbers when adding or multiplying the terms without changing the outcome. (a + b) + c = a + (b + c) Parentheses

These are symbols that are used to group numbers together in math expressions. 2)

Michael: (a)(b)(c)

Sadie: a + (b + c)

Ladonna: ab + c

Miguel: a(b + c)
