Order of Operations PEMDAS

Order of Operations The Order of Operations is the order of solving a mathematical problem. You must solve problems using the order of operations working from the left to right.

*Whichever comes 1st, left to right.* PEMDAS Use the acronym PEMDAS to help you remember the Order of Operations P – Parentheses E – Exponents M/D – Multiplication or Division *Whichever comes 1st, left to right.* A/S – Add or Subtract

1.) Parentheses ( ) Complete the math within the ( ) before you solve anything else. 11 – (2 + 4) 11 - (6) 5 Before you can do anything else, you must do the operation inside the parentheses.

After solving any problems in parentheses, solve all exponents. Clear(solve/evaluate) the exponents. 52 + 7 25 + 7 32 After solving any problems in parentheses, solve all exponents.

3.) Multiplication & Division Solve the multiplication and division from left to right in the order in which you find it. 36 ÷ 6 x 4 6 x 4 24 The 1st operation to do in this equation is division.

4.) Addition & Subtraction Solve the addition and subtraction, from left to right in the order in which you find it. 10 – 7 + 4 3 + 4 7 In this problem, you do the subtraction first because you solve from left to right.

(6 - 4) + 2 ÷ 2 2 + 2 ÷ 2 2 + 1 3

4 + 3(5-3) x 4 ÷ 2 4 + 3(2) x 4 ÷ 2 4 + 6 x 4 ÷ 2 4 + 24 ÷ 2 4 + 12 16

9 – (5 – 3)² ÷ 2 9 – (2)² ÷ 2 9 – 4 ÷ 2 9 – 2 7

You must follow PEMDAS within the parenthesis!!! Ready for a challenge???? Be Careful!!!! You must follow PEMDAS within the parenthesis!!! (12 – 4 x 2)² ÷ 2 (12 – 8)² ÷ 2 (4)² ÷ 2 16 ÷ 2 8

You must follow PEMDAS within the parenthesis!!! 3(8 + 8÷4) x 5 Again…… You must follow PEMDAS within the parenthesis!!! 3(8 + 2) x 5 3(10) x 5 30 x 5 150

15 + (16 ÷ 2²)³ 15 + (16 ÷4)³ 15 + 4³ 15 + 64 79
