What I wanted to do in this post is point out some of the differences to perhaps allows for a better decision. There are of course many online calculators as well, but obviously I am using hand-held models in this post for my comparisons. Mainly because not all students have consistent access to online tools (wifi) or phones (and phones are most often NOT allowed in class and definitely not on assessments), and the comparison between scientific vs. graphing is basically the same whether using an online version or a hand-held.

We are having a webinar tonight that explores the three models of scientific calculators that Casio offers, so if you are interested in finding out more about the capabilities, be sure to join us at 6:30 pm EDT (Register Here). We also did a previous webinar on the graphing calculator models, which I have included below. Hopefully now you can make some informed decisions. Check out all the calculators and pricing here:

There are some converters available to convert 128x64 (and that size only) black and white (monochrome) bmp files to G1M that can be opened on the calculator by calling them from the graph menu

(OPT RCLPICT)

I have to link to another site because the author of the program hasn't uploaded this program to UCF.

You can download a fileconverter here

Convert an image to monochrome bitmap. The file should be 128*64.

Select the BMP to G1M configuration in the program. Press GO and find the converted file.

Save the G1M file as PICT1 ~ PICT20.

You can put it on your calculator with the fa-124 and view it by entering the GRAPH menu and pressing

, PICT, RCL, and enter the desired number.

I could also write you a program to show plain (monochrome) BMPs on your calculator, but it would be a bit unhandy for you, since you'll need 2 add-ins for that.

Here's my attempt at simplifying things and adding in the DEG and RAD. I've made it so that RAD and DEG will always appear in the same place as they would on a real calculator. You could easily add other flags that might be needed (e.g., OCT and HEX) in the same manner.

Interesting Fact: The production debut of the Arithmometer in 1851 launched the mechanical calculator industry. The Arithmometer was the only type of mechanical calculator commercialized from 1878 to 1887 worldwide, and was still in use up to World War I.

A Brief History: The Casio fx-7000G was developed with 422 bytes of memory and could store up to ten programs in 10 program slots, according to the Computing History website. It offered 82 scientific functions, and its display could toggle between 8 lines of 16 characters each or a 64x96 dot matrix graphical display.

As previously mentioned, the NEWYES NY-991ES Plus Scientific Calculator features a total of 417 scientific functions which includes fractions, statistics, complex calculations of numbers, linear regression, basic arithmetic, computer science, standard deviations, polar-rectangular conversions, etc.

The course describes some of the main features of a scientific calculator and encourages you to use your calculator, both for everyday arithmetic and for more complicated calculations that use the function keys as well. Key sequences, which describe which keys to press, are included in all the activities, so you can try out the ideas straightaway.

Due to the wide range of scientific calculators available, for the purposes of this course we will be concentrating on the Casio fx-83ES model. Other calculators may function differently to the methods described within this course.

This calculator is used on the Open University courses Starting with maths (Y182) and Discovering mathematics (MU123), but would also be useful for many other courses requiring the use of a scientific calculator.

The first 11 sections describe how to use the calculator and how to perform different types of calculations. Section 12 contains a calculator reference guide that you can refer to as needed for some of the main key sequences.

The lower half of the keypad contains the number keys, keys for the basic operations of addition, subtraction, division and multiplication, and the key, which is pressed when you want the calculator to display the result of the calculation you have entered. The keys used to insert brackets into a calculation are in the centre of the row above the number keys.

Some calculator operations are accessed through a system of menus that are displayed on the calculator screen, as shown in Figure 3. The required menu option is selected by pressing the number key associated with the option, as given on the calculator screen.

The figure shows the display on a calculator screen containing four lines of text. The top row of the screen contains a downward pointing arrowhead towards the right end. First line of text is 1 : M t h I O (written as one word) space 2 : Line I O (written as one word). Second line of text is 3 : Deg space 4 : Rad. Third line of text is 5 : Gra space 6 : Fix. Last line of text is 7 : Sci space 8 : Norm.

The calculator has many modes of operation that affect how mathematics is entered and displayed. These will be described later in this guide, but before progressing any further you should reset your calculator to the default course settings.

Basic calculations are entered into the calculator in exactly the same order as they are written on paper, as demonstrated in the following activity. The calculator displays the calculation that you enter. When you press , the answer is displayed at the bottom right of the screen.

Note that the calculator uses the BIDMAS rules. These say that any expression within Brackets should be calculated first, then any Indices (often called powers), followed by Divisions and Multiplications and finally Additions and Subtractions.

There are several keys on the calculator that enable you to perform calculations involving powers. For small powers such as squares or cubes there are dedicated buttons, and , which are located in the function key area of the keypad. These are used in a similar manner to how you would write mathematics; for example, to enter you would press . The display also shows the maths in the same way as you would write it on paper.

In fact, some calculators permit the key to be used for both purposes, but many other calculators require the equivalent of the key to be used for negative numbers. For this reason we shall use to input negative numbers throughout this guide.

You may have been surprised that the correct answer to part (5) is negative. According to the BIDMAS rules, the squaring is performed first, then the negative taken. If we wanted to calculate the square of , we write this mathematically as and would need to use the brackets when evaluating it on a calculator.

You may have noticed that the results of both these exercises were displayed on the calculator as top-heavy fractions. This is the default behaviour of the calculator in Math mode. You can toggle between a top-heavy fraction and its mixed number equivalent using the key sequence .

The expression for the volume of wood requires the value of . You could enter an approximate value for by hand, but this is time-consuming and may be prone to error. The calculator has an approximation for built into it, which is obtained using the key sequence .

into your calculator and press . Can you explain why? Insert a pair of brackets into the expression with the sign so that it will give the correct answer. Then type this new expression into the calculator and check that you obtain the same answer as in the activity above.

(Note that on some later models of the calculator, the correct answer is obtained without adding the brackets to the denominator; however it is good practice to add the brackets to ensure the correct calculation is carried out).

You could write down the answer to the first part of the calculation on paper, and enter it into the calculator again. However, it is possible that you may make an error either in writing down the number or in typing it into the calculator. A better method is to use the fact that the calculator retains the last calculated answer, which can then be inserted in the subsequent calculation using the key located at the bottom of the keypad.

A variation on the above method is to break the calculation into two parts, and use the memory functions of the calculator to store the result of the first part. The calculator memory is particularly useful when you want to calculate the values of several expressions that have a common part. This common part need be entered only once and its value reused several times subsequently. For example, rewriting the formula for the volume of wood contained in a log as

In Activity 1 you will have already set your calculator to use Norm 2 mode, and we suggest that for the moment you continue to use this. To change the mode, use the key sequence (SETUP) (Norm) followed by (for Norm 1) or (for Norm 2).

Just as there are keys on your calculator for entering powers, roots can also be entered directly. Square roots can be calculated using the key. For example, can be entered using . Cube roots are entered using the second function of this key. For higher roots, such as fourth or fifth roots you need to use the more general template, which is the second function of the key. This template is filled in by using the number and arrow keys (and ) in a way similar to that used when the fraction template is completed. ff782bc1db
