Answer:_______________ |
| 1) Evaluate: 8 + 2 × 5 × 7 Answer: 78 SOLUTION 1 : Order of operations: 1. Multiplication and division Step 1: Multiply and divide from left to right. 8 + 2 × 5 × 7 8 + 10 × 7 8 + 10 × 7 8 + 70
Step 2: Add and subtract from left to right. 8 + 70 78 So: 8 + 2 × 5 × 7 = 78 |
| 2) Evaluate: 7 – 2 × 3 + 2 Answer: 3 SOLUTION 1 : Order of operations: 1. Multiplication and division Step 1: Multiply and divide from left to right. 7 – 2 × 3 + 2 7 – 6 + 2
Step 2: Add and subtract from left to right. 7 – 6 + 2 1 + 2 1+ 2 3 So: 7 – 2 × 3 + 2 = 3 |
| 3) Evaluate: 6 × 6 – 4 × 3 Answer: 24 SOLUTION 1 : Remember: Order of operations: 1. Multiplication and division Step 1: Multiply and divide from left to right. 6 × 6 – 4 × 3 36 – 4 × 3 36 – 4 × 3 36 – 12
Step 2: Add and subtract from left to right. 36 – 12 24 So: 6 × 6 – 4 × 3 = 24 |
| 4) Evaluate: 5 + 6 ÷ 6 × 6 Answer: 11 SOLUTION 1 : Order of operations: 1. Multiplication and division Step 1: Multiply and divide from left to right. 5 + 6 ÷ 6 × 6 5 + 1 × 6 5 + 1 × 6 5 + 6
Step 2: Add and subtract from left to right. 5 + 6 11 So: 5 + 6 ÷ 6 × 6 = 11 |
| 5) Evaluate: 8 ÷ 4 + 5 + 3 Answer: 10 SOLUTION 1 : Remember: Order of operations: 1. Multiplication and division Solve: Step 1: Multiply and divide from left to right. 8 ÷ 4 + 5 + 3 2 + 5 + 3
Step 2 : Add and subtract from left to right. 2 + 5 + 3 7 + 3 7 + 3 10 So: 8 ÷ 4 + 5 + 3 = 10 |
| 6) Evaluate: 6 + 5 × 4 × 5 Answer: 106 SOLUTION 1 : Order of operations: 1. Multiplication and division Step 1: Multiply and divide from left to right. 6 + 5 × 4 × 5 6 + 20 × 5 6 + 20 × 5 6 + 100
Step 2: Add and subtract from left to right. 6 + 100 106 So: 6 + 5 × 4 × 5 = 106 |
| 7) Evaluate: 8 – 2 × 1 + 6 Answer: 12 SOLUTION 1 : Order of operations: 1. Multiplication and division Step 1: Multiply and divide from left to right. 8 – 2 × 1 + 6 8 – 2 + 6
Step 2: Add and subtract from left to right. 8 – 2 + 6 6 + 6 6+ 6 12 So: 8 – 2 × 1 + 6 = 12 |
| 8) Evaluate: 8 × 8 – 2 × 4 Answer: 56 SOLUTION 1 : Remember: Order of operations: 1. Multiplication and division Step 1: Multiply and divide from left to right. 8 × 8 – 2 × 4 64 – 2 × 4 64 – 2 × 4 36 – 8
Step 2: Add and subtract from left to right. 64 – 8 56 So: 8 × 8 – 2 × 4 = 56 |
| 9) Evaluate: 7 + 3 ÷ 3 × 4 Answer: 11 SOLUTION 1 : Order of operations: 1. Multiplication and division Step 1: Multiply and divide from left to right. 7 + 3 ÷ 3 × 4 7 + 1 × 4 7 + 1 × 4 7 + 4
Step 2: Add and subtract from left to right. 7 + 4 11 So: 7 + 3 ÷ 3 × 4 = 11 |
| 10) Evaluate: 8 ÷ 4 + 1 + 5 Answer: 8 SOLUTION 1 : Remember: Order of operations: 1. Multiplication and division Solve: Step 1: Multiply and divide from left to right. 8 ÷ 4 + 1 + 5 2 + 1 + 5
Step 2 : Add and subtract from left to right. 2 + 1 + 5 3 + 5 3 + 5 8 So: 8 ÷ 4 + 1 + 5 = 8 |
