3. Do Now
Take out your foldable and your worksheet from yesterday. Begin by completing #1-13 on the back of the worksheet.

4. Introduction What does PEMDAS FLTR stand for? How do we use it?
How do we perform operations?

6. PEMDAS FLTR
In order to properly evaluate expressions, you have to use PEMDAS FLTR as a road map
Steps:
Identify the operations present
Complete operations with parenthesis and exponents
Perform multiplication/division simultaneously from left to right
Perform addition/subtraction simultaneously from left to right

7. Examples
10(5 + 2) – 32
Operations involve parenthesis, exponents, multiplication, and subtraction
Parenthesis first: 10(7) – 32
Exponents next: 10(7) – 9
Multiplication next: 70 – 9
Subtraction last: 61

8. Example #2
52 x (9 – 3 x 2) + 4 ÷ 2
Parenthesis first: 52 x (9 – 6) + 4 ÷ 2
Parenthesis again: 52 x (3) + 4 ÷ 2
Exponents next: 25 x ÷ 2
Multiplication/Division from Left next: ÷ 2
Division Again:
Addition Last: 77

9. More Practice Simplify each expression: 40 – 3 x 32 8 x 4 + 92
÷ 7 + 1
(17 – 7) ÷ 5 + 1
[10(9 ÷ 3 + 2) – (4 x 2)]
[10(9 ÷ 3 + 2) – (4 x 2)]2

10. 40 – 3 x 32

11. 8 x

12. ÷ 7 + 1

13. (17 – 7) ÷ 5 + 1

14. [10(9 ÷ 3 + 2) – (4 x 2)]

15. [10(9 ÷ 3 + 2) – (4 x 2)]2

16. Exit Ticket Simplify the following expressions 68 ÷ 2 + 10 ÷ 5
[20(5 - 3)2 – 75 ÷ 5] + (8 – 5)
