Order of Operations - Homework Due Nov 20th

Fill in the blank: PEMDAS, GEMDAS

• PEMDAS, GEMDAS

• BODMAS, GEMDAS

• PEMDAS, BEDMAS

• BIDMAS, PEMDAS

Answer explanation

PEMDAS and GEMDAS both represent the order of operations in mathematics, where P stands for Parentheses, E for Exponents, MD for Multiplication and Division, and AS for Addition and Subtraction. Thus, the correct choice is PEMDAS, GEMDAS.

What is the result of the expression 15 + 8² – (9 + 14)?

• 56

• 64

• 49

• 72

Answer explanation

First, calculate 8² = 64. Then, evaluate (9 + 14) = 23. Now, substitute: 15 + 64 - 23 = 56. Thus, the result of the expression is 56.

What strategy would you use this picture for?

• Sleepy Guy

• PEMDAS

• Rectangle

• The volume of a Rectangular Prism

Answer explanation

The picture likely illustrates the order of operations, which is represented by PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). This strategy helps solve mathematical expressions correctly.

Evaluate the expression using order of operations: 7 + 3² × (5 – 2).

• 34

• 28

• 16

• 25

Answer explanation

First, calculate the expression inside the parentheses: 5 - 2 = 3. Then, evaluate 3² = 9. Next, multiply: 9 × 3 = 27. Finally, add: 7 + 27 = 34. Thus, the correct answer is 34.

Use the order of operations to solve: (6 + 4)² ÷ 2 – 5.

• 45

• 50

• 40

• 35

Answer explanation

First, calculate (6 + 4)² = 10² = 100. Then, divide by 2: 100 ÷ 2 = 50. Finally, subtract 5: 50 - 5 = 45. Thus, the correct answer is 45.

Evaluate using order of operations: (8 + 2) × 3 – 5².

• 15

• 5

• 10

• 20

Answer explanation

First, calculate inside the parentheses: (8 + 2) = 10. Then, multiply: 10 × 3 = 30. Next, calculate the exponent: 5² = 25. Finally, subtract: 30 - 25 = 5. Thus, the correct answer is 5.
