9 Vocabulary Distributive Property (over addition)- states that to multiply a sum by a number, you can multiply each addend by the number, and then add those products together. “The Bottom Line”: The distributive property can make finding products easier!

13 (80 + 2) 3 × 3 × 2 = 6 246 + 3 × 80 = 240 3 × 82 = 246 Distributive Property of Multiplication over Addition.

14 Vocabulary Distributive Property (over subtraction)- states that to multiply a difference of two numbers by a third number, you can multiply the first two numbers by the third, and then find the difference of the products. “The Bottom Line”: The distributive property can make finding products easier!
