Sorry I never got a mail when you asked the question, I guess you've solved it by now...

any for anyone else who may have the same problem..you have fix selected(significant figures)

press the mode button top right, repeatedly until it displays Fix sci norm,
press the number underneath Fix which is probably 1
then press the number of decimal places you would like Between 0 to 9 yours at the moment is obviously set to 0

Sorry for being so late....

Hello,
To convert fractions to decimals or decimals to fractions, you use the [S<->D] key. Each time you press the key the result is displayed in the other format.
Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

Hope it helps.

If you want to get really basic and not mess around with a lot of fancy buttons and whatnot, simply put in 3.2 X 10 then push the ^ button and then (-)7. Over to the left, the third button down should look like ( - ), push that and then the 7 to avoid all the parethesis mistakes.

### How do i get the ee to work on my casio fx-115es plus?

What you call the EE ((entering power of 10 exponents) is done with the help of the key at the bottom right, and marked [x10^X].
To enter 6.02x10^23, you do as follows
6.02 [x10^X]23. When you use that short-cut key, no 10 should appear on the command line. See screen capture.

### Resetting casio FX-115W

Casio fx-115W was locked into some sort of mixed-up engineering output but without the exponent. There is no reset method to my knowledge but by removing the battery and putting the calculator in a drawer for 30 minutes then re-installing the battery the calculator reset to default values and works properly.

I checked in the manual and found that this calculator does not support Base-N calculations. On the FX-991ES Plus, which has a Base-N mode, fractions , exponents, and other floating points are not supported. The non-integer part is chopped off.

### I need step by step instructions on using Casio fx-115ES ee or exp burron.

The equivalent of the EE or EXP button on the Casio Fx-115ES is marked as x10^X. It is located at the bottom right of the key pad left of the = key.
To enter the power of 10 in a number written in scientific notation, you press the x10^X button followed by the exponent. If the exponent is negative you press the change sign key first [(-)] , then the one or 2 digits in the exponent.
Example Enter the mass of the proton m_p in kilograms
1.6726217 [x10^X] [(-)]27 [=]
In grams the value above is multiplied by 1000.
or
1.6726217 [x10^X] [(-)]24 [=]

Since the calculator has the physical constants (the FX-991ES definititely has them)
1. Display the proton mass in kilograms
2. [SHIFT ][7] to open the constants catalog,
3. type 01 for the proton mass, then press the [x^-1].
4. Divide the result by 1000
5. You should get 5.978638635 x10^23

You can set the number display mode to be SCI. Press [SHIF][MODE] and look for the number to the right of which is written SCI. Enter that number. You may be asked to specify the number of digits after the decimal mark 0 tilda 9. Select an appropriate number and enter the corresponding key.
If you want to ENTER numbers in scientific format, enter them the usual way. When you arrive to the power of 10 press the [x 10^X] key, followed by the exponent. Use the change sign key (-) to enter a negative exponent.

### Where is the exponent key on Casio fx-115es calculator?

To raise 10 to an exponent, use the 10^x function (SHIFT log). To raise e to an exponent, use the e^x function (SHIFT ln). To raise an arbitrary value to an exponent, use x^y (just above the sin key). To enter an exponent of ten, use the x10^x key to the right of the decimal point.

### Adding Exponents on a Casio fx-300MS

Hello,
The calculator applies the rules during the internal calculations. But all it shows you is the (final) result. It does not keep track of what exponents you used to get to the result. It is not capable of doing symbolic manipulations.
Hope you are not too disappointed.
