1. Order Of Operations

2. Why do we use it?
This is a way to solve equations according to a set of operations like multiplication, division, addition and subtraction. There is a specific order in which to solve the equations. Remember: “Please Excuse My Dear Aunt Sally.”

3. Remember….
PLEASE- parentheses EXCUSE- exponents MY – multiplication DEAR - division AUNT - addition SALLY-subtraction
PEMDAS

4. ALWAYS…
Complete the expression in that order. Look out for addition or subtraction in the same expression. Always move left to right. The same is true of multiplication and division. Always move from left to right!!

5. Let’s try some together… Use your whiteboards
Name the operation that you should do first.
6 + 27/3
5 x / 6
17 – (4 +3)

6. Use the order of operations to solve…
(14 -7) + ( 3 + 5)=
/ 3 x 5=

7. Who is Correct?
Two students completed the following problem: x 2 – 10 Student A answered with 3. Student B answered with 6. Who is correct and why? What did the student with the incorrect answer do wrong?

8. Explain Why?
