About the calculator.

This course assumes that you have a Casio calculator or have regular access to one.

It is primarily designed for the FX-83GT Plus / FX-85GT Plus available in the UK. Similar textbook display or Natural V.P.A.M calculators are known by different codes around the world.

FX-300ES Plus, FX-350ES Plus, fx-82DE PLUS, fx-82ES PLUS, fx-82ZA PLUS, fx-83GT PLUS, fx-85DE PLUS, fx-85ES PLUS, fx-85GT PLUS, fx-86DE PLUS, FX-95ES Plus, FX-500VN Plus, FX-82AU PLUS II and others

And silver edition models

FX-991ES Plus, FX-115ES Plus, FX-570ES Plus, FX-100AU PLUS, FX-991DE

What are the requirements?

  • You need to have a Casio Calculator as listed in the Full Details description or have use of one. This course can be completed by anyone, from experienced to beginner. This course is also an excellent follow-up to the Essential Casio Calculator Skills Course.

What am I going to get from this course?

  • Use your Casio scientific calculator with confidence both in the classroom and during exams.
  • Explore mathematics in new and practical ways with the unique features of the Casio calculator.
  • Access all the unique and powerful functions of a modern scientific calculator.
  • Apply your knowledge of these calculator functions to questions you might encounter in your math related course.

Who is the target audience?

  • School and college students (typically 16+) studying a mathematics course (or a course with mathematical content), who would like to develop their knowledge of using a scientific calculator effectively. This may also include university students who are required to use a scientific calculator, rather than a graphing calculator.
  • Teachers or lecturers involved in teaching mathematics to students, who wish to develop skills using a scientific calculator.
  • Any other professionals who are required to use a scientific calculator or anyone interested in improving calculator and mathematical skills.
  • This particular course is designed for use with the Casio Natural VPAM model of calculator, specifically the fx-83GT Plus, fx-85GT Plus and fx-300ES PLUS. If you have another model of scientific calculator, whilst you may find some of the lectures applicable, they may not exactly match the location of the features and functions of your particular calculator model.
  • How is this course different from Essential Casio Calculator Skills? - This course dives deeper into the features of the calculator. This course looks at logarithm functions, trigonometry, radians, simultaneous equations and much, much more that is not covered in the Essentials course. This course is also more likely to feature additional material in the future.
  • What do I get from completing this course? - Greater confidence in mathematics lessons and in exams. Quicker and speedier calculations mean less time wasting. Using your calculator effectively may help to reduced your anxiety about certain topics and help you solve problems more effectively.

Section 1: Welcome and get ready to start getting more out of your calculator.

Who's this course for and what are you set to learn?


Resetting you calculator is important if you are ever unsure about the settings or mode your calculator is currently in. It is often also a requirement before an exam.

Section 2: The Setup Menu - Setting the calculator up as you want it!

The First Setup Menu enables you to switch between the text book display MATH mode and the more traditional LINE display. Change your angle measurements between degrees radians and even gradians. You can also choose the number of decimal places to display a number to.


I refer to Standard Index Form in the video as it is known as this in the UK. You may also know this as Science Notation (Hence it being Sci mode!)


How can the calculator present numbers in standard from 9science notation)? It also can round the number for you.


If you press down when you access SET UP, you will see a second menu, with the ability to refine features such as the screen's contrast, or add frequency to your STAT mode functions.

2 questions

Test your knowledge of the SETUP menu.

Section 3: Indices and Logarithms

There are several buttons available to deal with numbers with powers. We explore the input any power button and the reciprocal button.


You should notice a button which looks like this...(-) on the right hand side.

This is the best button to use when inputting negative numbers, rather than the subtract button.

The button itself suggest you can put brackets/parentheses around the negative sign.

This is essential when raising negative numbers. For example

-6² will give you the answer -36

(-6)² will give you the answer 36.

If you wanted the square of the number negative 6, the second result is correct. The calculator will prioritise powers before negatives, so be careful.


There are two buttons that enable you to input logarithms, one is more traditional whilst one capitalises on the textbook display of the calculator.


You can change the standard log button from using the default base of 10.


The Natural logarithm (ln) and Euler's number (e) are inverse functions. This lectures uses the calculator to explore the relationship.

3 questions

How well do you know the log functions?

Section 4: The Trigonometric Functions

Exploring Sin, Cos and Tan and how to obtain the reciprocal functions Sec, Cosec and Cot.


A breif look at where to find the hyperbolic functions.

The Factorial function and combinations and permutations.
3 questions

Test your knowledge on the various functions you have just learned.

Section 6: STAT Mode

You can create frequency tables in STAT mode by switching the frequency function on. You can then calculate the sum and mean of data in frequency tables and grouped data through use of the mid-point.

Turning frequency off
Linear Regression and related features
STAT mode quiz
2 questions
Section 7: TABLE Mode
Exploring and Discovering Roots Using Table Mode

Finding two roots means more work for you to do. Find out what you can do if you don't find a root with your first trail range.


Can TABLE mode help with simultaneous equations? Find out here how you can use TABLE mode and a Trial and Improvement method to find solutions to simultaneous equations.

Section 8: Extra Content - Discover more about your calculator

As mentioned earlier in the course, you can find out how to switch between MATH and LINE display.


See how you can use the standard form (scientific notation) feature of the calculator to complete calculations.


Lost your dice? You can use your calculator instead. See how you can use the random integer feature to simulate 1 or two dice.

Extra Video - Using Pol function to find the length of the hypotenuse
Extra Video - Iteration using Ans button

Discover how you can enter diagnostic mode and test your calculator's functionality.

What about VERIFY Mode?

Some of the extra features that are available on the fx-300ES PLUS and some other models. Download this pdf for the interactive content.

Please do not redistribute or upload to other platforms.


If you have the UK edition or a version that does not have the dedicated GCD and LCM functions above the x and ÷ buttons, this trick can help you find the highest common factor and least common multiple.

Instructor Biography

Steven Gardiner, Online Instructor and Mathematics teacher

I have been teaching mathematics for over seven years and am excited about teaching students how to get more out of using technology for learning, specifically their calculator. I started The Calculator Guide, a growing collection of videos and resources in February 2015 and am happy to be developing courses online and on Udemy.

I have recently completed an MSc in Mathematics Education where my dissertation examined students perceptions and knowledge of a Natural Display Calculator and explored new ways of using the calculator to help students and teachers.
