1. Order of Operations and the Distributive Property COURSE 2 LESSON 1-9 Use the Distributive Property to find 7(52). What you think 52 is 50 + 2. Finding 7(52) is the same as finding 7(50) + 7(2). This I can do mentally, so 7(50) + 7(2) = 350 + 14, or 364. Why it works 7(52) = 7(50 + 2) = 7(50) + 7(2) Use the Distributive Property. = 350 + 14Multiply. = 364Add. 1-9

2. Order of Operations and the Distributive Property COURSE 2 LESSON 1-9 Use the Distributive Property to find 4 4.8. What you think I think of 4.8 and 5.0 – 0.2. Then, 4(4.8) is the same as 4(5.0 – 0.2). I know that 4(5.0) – 4(0.2) = 20 – 0.8 = 19.2. Why it works 4(4.8) = 4(5.0 – 0.2) = 4(5.0) – 4(0.2)Use the Distributive Property. = 20 – 0.8Multiply. = 19.2Subtract. 1-9
