4. Parenthesis
( 5 x 4)
You solve whatever problem is in side the parenthesis first.
K. Hall

5. Exponents
An exponent is the number that tells how many equal factors there are.
For example:
10 x 10 x 10 x 10 = 10 4
K. Hall

6. Multiplication OR Division
You need to complete multiplication OR division which ever comes first in the problem.
5 x – 2 =
5 x 4 is going to be the first thing you solve in this problem because you solve multiplication or division which ever comes first in the problem.
K. Hall

7. Addition OR Subtraction
When you arrive at this step of the process you should not have any parenthesis, exponents, multiplication or division left in the problem.
Solve addition or subtraction ONE AT A TIME which ever comes first in the problem. –
19 –
= 27

8. Comparing
The signs < and > are used to compare two things in math.
> means greater than
< means less than
An easy way to remember these is that the alligator mouth will eat the bigger of the two things that you are comparing.
K. Hall

9. Comparing Using The Order of Operations
You can also compare numbers using the Order of Operations.
You solve both sides of the problem using the order of operations and decide which number is greater when you complete the Order of Operations.
For example:
2 + 5 – (4 x 2)
– 1
– 1
9 < 12
