3. Order of Operations PEMDAS

4. 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.

5. *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

6. 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.

7. 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.

8. 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.

9. 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.

10. (6 - 4) + 2 ÷ 2
2 + 2 ÷ 2
2 + 1 3

11. 4 + 3(5-3) x 4 ÷ 2
4 + 3(2) x 4 ÷ 2
4 + 6 x 4 ÷ 2
÷ 2
4 + 12 16

12. 9 – (5 – 3)² ÷ 2
9 – (2)² ÷ 2
9 – 4 ÷ 2
9 – 2 7

13. 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

14. 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. 15 + (16 ÷ 2²)³
15 + (16 ÷4)³
15 + 4³ 79
