Order Of Operations
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

Remember….
PLEASE- parentheses
EXCUSE- exponents
MY – multiplication
DEAR - division
AUNT - addition
SALLY-subtraction
PEMDAS
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!!
Let’s try some together…
Use your whiteboards
Name the operation that you should do first.
1. 6 + 27/3
2. 5 x 2 + 12 / 6
3. 17 – (4 +3)
Use the order of operations to solve…
(14 -7) + ( 3 + 5)=
36 + 9 / 3 x 5=
Who is Correct?
Two students completed the following problem:
3 + 5 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?
Explain Why?
Test to see if the following equation and answer
is accurate.
( 3 + 4 x 5) + 6 = 29
What was the first operation that you
