Order of Operations
The Order of Operations is the
order of solving a
mathematical problem.
You must solve problems using
the 6 operations, working from
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
A/S – Add or Subtract
PEMDAS = Parentheses ( )
Parentheses are the 1st operation to look for in a
problem. If there are parentheses then you must do
the math in them before anything else.
Ex: 11 – (2 + 4)
2+4=6
11 – 6 = 5
Before you can do
anything else, you
must do the
operation inside the
parentheses.
PEMDAS = Exponents
The 2nd operation to look for in a
problem are exponents. If there are
exponents solve them next.
Ex: 52 + 7
52 = 25
25 + 7 = 32
After solving any
problems in
parentheses, solve all
exponents.
PEMDAS = Multiplication +
Division
Multiplication and Division are the 3rd
operations to look for in a problem. Solve
multiplication and division problems
working from left to right.
Ex: 5 x 6 + 12
5 x 6 = 30
30 + 12 = 42
Ex: 36 ÷ 6 – 4
36 ÷ 6 = 6
6–4=2
The 1st operation to
do in this equation is
multiplication.
The 1st operation to
do in this equation is
division
PEMDAS = Addition +
Subtraction
The last two operations to look for
in a problem are Addition and
Subtraction. Solve these after
completing all of the math in
Parentheses, Exponents,
Multiplication, and Division.
Ex: 5 + 4 – 6
5+4=9
9–6=3
Ex: 10 – 7 + 4
10 – 7 = 3
3+4=7
In this problem you do
the Adding first
because you have to
go from left to right.
In this problem though,
you do the subtraction
first because you solve
from left to right.
