Mastering the Order of Operations

What is the result of 3 + 2 * 5 according to the correct order of operations?

• 10

• 30

• 13

• 25

What is the purpose of the order of operations in mathematics?

• To ensure consistency and clarity in solving expressions

• To allow for multiple interpretations of an expression

• To make calculations more complex

• To prioritize addition and subtraction over other operations

Which operation should be performed first according to the order of operations?

• Parentheses

• Multiplication

• Subtraction

• Addition

What is the effect of using parentheses in mathematical expressions?

• It only affects addition and subtraction

• It specifies the operations to be performed first

• It has no effect on the order of operations

• It indicates the operations that should be performed last

What does PEMDAS stand for?

• Parentheses, Exponents, Multiplication, Addition, Subtraction, Division

• Parentheses, Exponents, Division/Multiplication, Addition/Subtraction

• Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

• Parentheses, Exponents, Multiplication/Division, Addition/Subtraction

Why are multiplication and division treated equally in the order of operations?

• Because division is just multiplication by a fraction

• Because they are performed based on their appearance from left to right

• Because they are performed from right to left

• Because both operations are forms of addition

Which of the following is true about the division and multiplication in the order of operations?

• Multiplication is always performed before division

• Multiplication and division are performed based on their order from right to left

• Multiplication and division are performed based on their order from left to right

• Division is always performed before multiplication

In the expression 2 * 10 - 8 / 4 + 1, what is the correct first step?

• Divide 8 by 4

• Multiply 2 by 10

• Subtract 8 from 10

• Add 1 to 4

What is the final result of the expression 2 * 10 - 8 / 4 + 1?

• 11

• 19

• 20

• 5

How can you ensure that addition is performed before division in an expression?

• By enclosing the addition operation in parentheses

• By using a fraction sign

• By performing the division operation last

• By placing the addition operation at the end
