-Demonstrate an expression that uses the distributive property to reach the same solution that you would using the order of operations. -Give an example of a real life situation that could be used to represent the distributive property. -Show how to solve the following expression using the distributive property: 14(x - 4) -How do I know when the distributive property can be applied? Notes: The factor on the outside of the parentheses is used to multiply the terms inside the parentheses. The factor may be on either side of the parentheses, left or right. To use the distributive property, the terms inside the parentheses must be adding or subtracting. Practice: Done through warm-up as well as further practice on Friday. |
