Introduction to order of operations | Arithmetic properties | Pre-Algebra | Khan Academy

Why is there an agreed-upon order of operations in mathematics?

• To make mathematical problems more challenging.

• To ensure everyone gets the same answer for a mathematical expression.

• To allow for different interpretations of the same problem.

• To prioritize addition and subtraction over other operations.

Which list correctly shows the order of operations?

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

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

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

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

What is the correct value of the expression 7 + 3 × 5?

• 50

• 22

• 15

• 10

Which of the following lists the mathematical operations in the correct order of priority?

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

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

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

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

What is the first step to solve the expression (7 + 3) × 4 ÷ 2 - 5 × 6?

• Multiply 5 by 6

• Add 7 and 3

• Divide 4 by 2

• Subtract 5 from 2

When an expression has both multiplication and division operations, how should you decide which one to do first?

• Always do multiplication before division.

• Always do division before multiplication.

• Perform the operations from left to right.

• Perform the operations from right to left.

If an expression only contains addition and subtraction, what is the correct way to perform these operations?

• Always do addition before subtraction.

• Always do subtraction before addition.

• Perform the operations from left to right.

• Perform the operations from right to left.
