2. Solve the following problem. 10 – 3 2 + 2 ÷ 2

4. Order of Operations 1. Simply expressions within grouping symbols. ( ) [ ] 2. Simply exponents. 3. Multiply & divide from left to right. 4. Add & subtract from left to right. Examples: (8 + 4) 328 ÷ (7 2)14 – (8 - 6) 5 Practice Worksheet

5. Warm Up Solve: Remember PEMDAS 30 ÷ (3 + 2) 6 18 - 9 + 3 (5-1)

6. Distributive Property a(b+c) = a(b) + a(c) a(b -c) = a(b) + a(c) Examples: 9 (4 + 5) = 9(4) + 9(5) = 36 + 45 = 81 5 (8 – 2) = 5(8) – 5(2) =

7. Distributive Property in Mental Math Use the distributive property to find 4(36) What I’m thinking……. 36 is 30 + 6, so finding 4(36) is the same as finding 4(30) + 4(6). This I can do mentally! 4(30) + 4(6) = 120 + 24 = 144
