2Order 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.
3PEMDAS
- 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
-
4PEMDAS 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.
5PEMDAS 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.
6PEMDAS 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
7PEMDAS 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.
