P.E.M.D.A.S
By: Samuel Corso

What is P.E.M.D.A.S?
P.E.M.D.A.S is the acronym we use to explain the order of
ooperations. The order of operations are Parentheses,
Exponents, Multiply, Divide, Add or Subtract. We must use
this order to solve problems with multiple sign being used.

Parentheses
You may see Parentheses like ( or ) to show that this is part
of the problem that must be computed first. Parentheses
may go around multiple numbers and signs.
Example:
(9+67)x36
76x36=2736

Exponents
Exponents are basically the fancy name for powers on
numbers. They mean that there is a number raised to a base
number. To show an exponent you may use a sign like ^
before the power.
Example:
7^2x4
49x4=196

Multiply
The next stetp to P.E.M.D.A.S is to multiply, then divide to
make the equasion easier, but you may also multiply or
divide left to right. Multiplication is done normally in order
of operations.
Example:
9x5-3
40-3=37

Divide
After multipling, its time to divide. Dividing is also done
regularlly in order of operations. We should divide left to
right, but it is not necessary.
Example:
6/3-1
2-1=1

Add
Now it is tiime to add. We can add or subtract left to right,
but is usually easier to add first. We add normally.
Example:
7+4-3
11-3=8

Subtract
The last step before computing your answer is to subtract.
As I said, we do not need to subtract for multiplying going
left to right, but you may. Subtract normally, then its time
to compute your answer.
Example:
7-5+4
2+4=6

Check
One important thing to do once you have computed your
answer is to check it. First, check your math with a
calculator, then make sure that you have answered the
question entirely.
Example:
First Answer Once Checked
3x4/6-1 3x4/6-1
12/6-1 12/6-1
6-1=5 2-1=1

My Question
What is (5+21)x(6/2)-4 ? Remember to check!
