PEMDAS

The PEMDAS rule is an acronym representing the order of operations in math:

• Parentheses
• Exponents
• Multiplication and Division (from left to right)
• Addition and Subtraction (from left to right)

Given expression:

72 - 9 ÷ 3 · 2 + 2

Following the order of operations, carry out the multiplication and division first, working from left to right.

Divide 9 by 3:

⇒ 72 - 9 ÷ 3 · 2 + 2

⇒ 72 - 3 · 2 + 2

Multiply 3 by 2:

⇒ 72 - 3 · 2 + 2

⇒ 72 - 6 + 2

Now carry out the addition and subtraction, working from left to right.

Subtract 6 from 72:

⇒ 72 - 6 + 2

⇒ 66 + 2

Add 66 and 2:

⇒ 66 + 2

⇒ 68

Solution

72 - 9 ÷ 3 · 2 + 2 = 68
