IN SHORT, YOUR
CALCULATOR CAN DO JUST
ABOUT ANYTHING
(RELATED TO MATH) AS
LONG AS YOU KNOW HOW
TO USE IT! THIS PACKET
WILL TEACH YOU SOME OF
THOSE SKILLS!
BASIC MATH COMPUTATIONS
You can use the calculator to complete most of your calculations on the test. The
screen on the calculator is user friendly and helps show s you exactly what you have
typed in. Always remember to push the ‘enter’ button in the bottom right hand
corner. Play around with the calculator for a few minutes and once you think you
have the hang of the basic functions try these questions out below using your
calculator (Round to the nearest hundredth and use the answer bank for help!)

HELPFUL HINTS:
-You do not have to type in any commas into a calculator but you must remember
where the commas go
-Multiplication is sometimes shown as * instead of x
-Division is sometimes shown as / instead of ÷
-Always double check your work to ensure you type in the numbers correctly!
- Remember 34 is like typing in 3 x 3 x 3 x 3 into your calculator. Practice This!
ORDER OF OPERATIONS QUESTIONS
Do you remember Chapter 8? If you have not done Chapter 8 yet it is about the Order of
Operations for math problems. You must complete the problems in a certain order to get
the correct answer. In order to answer correctly you must follow the procedure on the
right. The calculator is so smart that all you
have to do is type in the expression (the
whole problem) and push ‘enter’ and it will
complete the problem in the proper order for
you! Use the calculators to solve these
problems and if you know how to complete
the work on paper and pencil, double check
the calculator’s answer to see if it is correct!

HELPFUL HINTS:
-Remember to always type in the parentheses shown in the problem!
-Type in the entire problem before pushing enter
-Double check to make sure you typed in the problem correctly!
ADDING & SUBTRACTING FRACTIONS
Adding and subtracting fractions is a piece of cake if you use the calculator! The
most important thing you need to know is how to type fractions into the calculator
(it can be confusing and take time to master this skill). Please watch Mr. Freeman
do examples on the board and do them with him to ensure that you know how to do
it yourself. Once you have seen Mr. Freeman demonstrate several problems, you
are free to complete the problems below for extra practice. If you need help ask a
neighbor or Mr. Freeman.

There are many other functions and types of questions your calculator can help you
answer! Try using the % key, exponent keys, square roots, or other functions that
you see. If you have questions on how to use your calculator, please ask Mr.
Freeman, Mrs. Molnar, or Mr. Jones.
YOUR TURN!
You have practice solving several different types of questions and now it is your
turn to try and stump your neighbor. Write 10 questions below and switch your
packet with a neighbor and solve their questions! Be sure to give them answer
choices in the Answer Bank to help (hint: you need to know the answers in order to
put the answers in the answer bank!)
