Help Your Child Understand the Order of Operations for Math Class
That is one math saying that always stuck with me and helped me out tremendously when I had to solve multi-step problems. Now that I have passed it on to my son, he doesn’t struggle with it anymore. That’s why I decided to pass it on in hopes it will help other people.
When working with multi-step problems you must use the order of operations or else you will end up with the wrong answer. That’s where the order of operations comes into play.
Step 1 – You must always do the problem in parentheses first.
Step 2 – Then do your exponents.
Step 3 – Next do your multiplication and division from left to right.
Step 4 – And last do addition and subtraction from left to right.
In order to remember those four steps, Just remember “Please Excuse My Dear Aunt Sally.”
Please = Parentheses
Excuse = Exponents
My = Multiplication
Dear = Division
Aunt = Addition
Sally = Subtraction
For example…
8 x ( 5 + 16 ) / 4 – 2 =
First do the parentheses.
8 x ( 5 + 16 ) / 4 – 2 =
21
Since there is no exponents we move to the multiplication.
8 x 21 / 4 – 2 =
168
Now we do division
168 / 4 – 2 =
42
Since there is no addition we move to subtraction.
42 – 2 =
40
So your answer to
8 x ( 5 + 16 ) / 4 – 2 = 40
I hope this helps more kids the way it has helped mine. Math can be fun if you make it fun.
