Question about Casio FX-115ES Scientific Calculator

I have tried the shift 9(clear)1(setup)= but this will not get the calculator back to computation mode.

Every time my student puts in a decimal addition problem the answer comes up as a fraction. Help?

Press [SHIFT][9] (CLR). Then select 3:All.

Everything will be reset to default.

To setup press [SHIFT][MODE](Setup) and change the

settings you want.

1: to use MathIO display mode; 2: to use the LineIO, 3: 4: 5: to change the angle unit. 6:Fix to set Fixed number of decimals, 7:SCI scientific notation display, 8: Norm for Normal display mode. (read your manual for that).

By pressing the Arrow Down button you get other setup choices.

1: to display mixed numbers, 2: for improper fractions, 3: Stat; 4: to chose the dot or the comma as a decimal marker. 5: to adjust contrast of the screen.

Hi ceanelson,

First, I would clear the memory. Press [SHIFT] [9] (CLR) [1](Setup) [=] (YES). Then press [SHIFT] [MODE] [2] to switch to the LineIO mode. Put the calculator in Norm2 mode. I just like the way it display these kind of numbers in Norm2 mode. Press [Shift][Mode] [8] [2] for Norm2. Next check make sure FIX mode is greater than at least 5. I usually select FIX 9 but, 5 seems to be good for must non-essential calculations. Next, press [2] [.] [5] [*10^] [(-)] [2] [=]. You can use the [SHIFT] [LOG] for the 10^ and, I usually do instead of [*10^] key.

Next, when dealing with numbers like these, I always use brackets. Such as press [ ( ] [2] [.] [5] [*10^] [(-)] [2] [ ) ] [=]. This is because, if you divide or do some other math operation you want to keep this number as a whole complete number. The calculator tends to break numbers like these up and, you do not want that to happen. It's a good habit to get into. Post a comment on any questions you may have and, I'll respond quickly.

I believe your calculator is set up to do TABLE computations. In these computations you enter the function for which you want a table generated.

Press [SHIFT][9] to clear/reset the calculator. You should find a CLR marking on calculator near the 9 key.

You can also press [MODE] button and select [COMP], which is the general computational mode.

Press [SHIFT][MODE] to enter (SETUP) and select [2:LineIO]

The calculator has two input/output (I/O) modes: MthIO and LineIO.

MthIO is a very nice novelty: it allows one to enter expressions as with pen and paper (textbook display). Results are displayed, whenever possible, as exact values ie fractions and radicals.

MthIO is the default I/O mode of the calculator. If it is not set, you can set it by pressing [SHIFT][MODE] (SetUp) to access a list of choices. Select [1:MthIO].

The other I/O mode is the old way of doing things: every thing is enter on the same level line, while in MthIO you have textbook style templates. In LineI/O all results are displayed as decimal (approximate) values.

To set LineIO press [SHIFT][MODE](SetUp) and select [2:LineIO].

If the displyed result is fresh you can toggle between decimals and fractions/radicals by pressing the [S<=>D] key.

Even if you are in MthIO you can force the (final) result into decimal display format by pressing, NOT the = sign, but [SHIFT][=] .

Pi, being a transcendental number, cannot be represented as a fraction. There must be something you forget to tell us.

The normal behavior of the calculator is as follows.

I have no idea why your calculator is behaving as you say it does, maybe it is defective, and should be returned.

However, here is again how to set the calculator. (Just ignore what I say, if you know how to do it. Others may find it helpful).

To set MthIO: [SHIFT][MODE] (SETUP) then [1:MthIO]

The other Input output mode is LineIO, the old way to enter expressions in a calculator. In this mode no results are displayed as fractions or radicals, just decimal values.

To set LineIO: [SHIFT][MODE] (SETUP) then [2:LineIO]

The normal behavior of the calculator is as follows.

- In MthIO mode, [SHIFT][Pi][x] 9 = 9Pi.
- In LineIO mode, [SHIFT][Pi][x] 9 = 28.274 if the number of decimal digits is 3

I have no idea why your calculator is behaving as you say it does, maybe it is defective, and should be returned.

However, here is again how to set the calculator. (Just ignore what I say, if you know how to do it. Others may find it helpful).

- Full reset: [SHIFT][9] (CLR) [3:All][= Yes] [AC]. The default input/output mode will be the MthIO. In MthIO, you have several templates to enter expressions as you would with pen and paper (textbook display). Fractionary results are displayed as reduced fractions and radicals are displayed as radicals (no decimal display).

Hello,

Regardless of the way it looks, this huge number is just 1, written in scientific notation, with 9 decimal digits. This is due to the configuration of your calculator.

To revert to the default display mode, press [SHIFT][MODE][6:Fix] and select a number of decimal digits between 0 and 9.

If you do not like the [MathIO] (fractions, radicals) you can use the [SHIFT][MODE][2:LineIO]

Hope it helps.

- Calculator must be in SD mode (standard deviation mode) :Press [MODE] [.]
- However, if [FIX] or [SCI] appears on display you must press [MODE][9] first.
- Data input always starts with [SHIFT][SAC], to clear the registers of old data.
- Type a number and press the [DATA] key, it is the [M+] key at the bottom right of keypad.

Press [SHIFT] [9] (sigma n-1) to get sample standard deviation

Press [SHIFT][8] (sigma n] for the population standard deviation

Press [SHIFT] [7] (xbar) for the mean

Press [SHIFT] [6] (n) for the number of data entries

Press [SHIFT] [5] (capital sigma x) for the sum of values

Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values

For additional information you might consider taking a look at the calculator manual
