Please could you tell me how to reset this calculator? Back to factory settings?

oh there is something else wrong other than the settings, as I have re set and it is still not working correctly.

if i divide 500 by .4 it brings it to a fraction, this is fine as I press S-D but it then turns it into the following answer 8x10to the power of negative 4!!!

I am looking to convert it back to .0008

How can I do this?

• Andiec Nov 15, 2007

its ok I have fixed my problem, it was due to the amoutn of decimal places I had my calculator set to show, I have set it to 9 so its fine now.

I do not have my instruction book any more. I was wondering if I could get a new one, or a copy of one. I would be really helpful so I can fix my problen which is that I can't divide numbers that don't go into eachother equally. For example 47 divided by 7 comes out to be 47 over 7. An instruction book would be great thanks.

Need to reset decimal on my BA II Plus. Cannot figure it out..

• Anonymous Dec 03, 2007

I have this same problem, where the calulator shows me the fraction instead of the decimal number. I tried changing the number of decimal places and it didn't work.

Any other ideas?

I have a calculator CASIO fx-9750GA. I want to convert certain decimals into fractions and when I press the d/c button it says "SYN error" I don't know what that is? I tried pressing Shift and then the Set-up button and the first option is Mode and the one below it is Func Type. Across from Mode it says "comp" I don't know how to change from there either. Please help. I rather use the d/c button, why is it not working?

Try removing its batteries first.

if you don't feel like removing the battery then perform this operation!

SHIFT 9 (CLR) 3 (ALL) = YES

This will initialize the calculator and return the calculation mode and setup to its initial default setting. this will also clear all data currently in the calculator.

Switch it on, press SHIFT button then Mode/Setup button (top right corner) then press 2 to put it in LineIO mode.

### Hi there, i have the same problem with the Casio fx 83ES. Simple Sums difficult without Exp?

The Enter Exponent key may be marked as x10^x. It is in the last row of keys, near the =/EXE. To enter a negative exponent use the change sign key (-), not the minus key for subtractions.
