• Multiplication, Addition, Division, Exponents

• Exponents, Parentheses, Addition, Subtraction

What is the result of the expression 10 + 15 ÷ 5?

• 12

• 13

• 14

• 15

What is an example of an expression that requires the order of operations?

• 8 + 2 x (3 - 1)

• 5 + 3 - 2

• 10 / 2 + 4

• 6 x 2 - 1

What is the first step in simplifying the expression 3 + 4 x 6 - 4?

• Perform the addition: 3 + 4 = 7

• Perform the multiplication: 4 x 6 = 24

• Perform the subtraction: 6 - 4 = 2

• Perform the division: 4 / 2 = 2

How do you handle parentheses in an expression?

• Simplify the expression inside the parentheses first before applying the order of operations to the rest of the expression.

• Apply the order of operations to the entire expression without considering the parentheses.

• Ignore the parentheses and simplify the expression from left to right.

• Always evaluate the expression outside the parentheses first.

Why is it important to follow the order of operations?

• It allows for multiple correct answers.

• It ensures that mathematical expressions are evaluated consistently and correctly, leading to the correct answer.

• It simplifies all mathematical expressions automatically.

• It is only necessary for complex calculations.

Can multiplication and division be performed in any order?

• Yes, they can be performed in any order.

• No, they should be performed from left to right as they appear in the expression.

• Multiplication should be done before division regardless of order.

• Only division can be performed before multiplication.

What is the result of the expression (4 x 8) - (9 + 7)?

• 12

• 14

• 16

• 18

How can you check your work after solving an expression?

• By ignoring the order of operations and re-evaluating the expression randomly.

• By re-evaluating the expression step by step, ensuring that you followed the order of operations correctly.

• By asking a friend to check your work without showing them the expression.

• By using a calculator to verify the final result only if you have time.

Can addition and subtraction be performed in any order?

• Yes, they can be performed in any order.

• No, they should be performed from left to right as they appear in the expression.

• Yes, but only for simple calculations.

• No, addition can be performed before subtraction regardless of order.
