    Can anyone help with scientific calculator 22nd Nov 17 at 2:20 PM
    I'm afraid it's not exactly eBay related but anyhow, bought a scientific calculator (on eBay lol)


    and I have never used one before. When you put in a figure and calculate a percentage such as VAT, if it's a whole number the answer appears correctly but if not it comes out as a fraction so:


    75+20% comes out as 376 over 5.
    Does anyone know how to resolve this?

    What does it do if you input 75 x 20% + =

    Or can you press the fraction button again for it to show decimals?

    I have a fraction button on mine that I press for fraction and again for decimal.

    Alternatively have you got a MODE button?

    What is the make/model, perhaps google can help.

    Press Shift then Mode/Setup to access Setup.
    Select 'MthIO' (option 1 on mine)
    then Select 'Line0' (option 2 on mine)
    You should now get decimal outputs.

    Secondly, when you type "20%" it evaluates that as "20% of 1"
    so 75+20% will come out as 75.2 which is not what you wanted.

    To add 20% to the original price you should just multiply by 1.2

    75 x 1.2 = 90

    That's amazing lammy82. It's also fixed my fx-83GT PLus. That's why I bought another one on the first place! lol Now I have two calculators.

    You can get the answer in decimal form by pressing the S<>D button (just above DEL). Repeated presses switches between the formats.

    You don't need a scientific calculator to do percentages though - any calculator can do the job (as lammy says, just times your price by 1.2).

    Don't know if this will be of help, but you can download the manual direct from Casio at http://support.casio.com/pdf/004/fx-82ES_83ES.etc_Eng.pdf

    Come on people, it's not difficult: lose means to be unable to find, loose means not being fixed in place. So if you have a hole in your pocket you might lose your loose change.

    You haven't seen my phone. It's the next model up from two plastic cups connected by a piece of string. :/

    Can’t you just do Price x 1.2 if you want to work out the price + VAT?

    That must be it then. That was my other CASIO which must be about 35 years old.

    My first calculator would also do that, a Prinzsound (Dixons) from the early 1970s.
    Only packed up about 10yrs ago after a battery leaked.

    Sub £5 Casio MX-85 works if you put 100+20% instantly displays 120

    Bought from ASDA a few months back.

    Surely by the time you've found the calculator and effed around with it it's faster to do it in your head.
