Question about Casio FX-115ES Scientific Calculator

# Problems with fractions on the Casio fx-115es

I just recently purchased the Casio fx-115es for a math class I am taking. We are starting fractions and I cannot get my calculator to give me an answer. It just restates the fraction or gives me an improper fraction. Is there a special key I have to press to get the correct answer? (I am trying to multiply and divide fractions.)

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.

### How do i remove MATH deplay on my Casio FX115ES

Press [SHIFT][MODE] to enter (SetUp). Select [2:LineIO] and you will be rid of the MATH Input/Output. You will lose some nifty features, like the stacked fractions, the radicals, but that is your choice.

Cheers.

### I was just wondering how exactly to get the fraction bar on the fx-115LS model so I can do out a problem for my math homework.

Set the calculator's Input/Output Mode to MthIO. In that mode the key that is marked with the icon of a fraction ( a bar, two rectangles, one above the bar, the second below it) will display the template of a fraction. You are supposed to enter the numerator in the upper rectangle, and the denominator in the lower rectangle.

### How to change or put math mode without fractions or scientific notation on calculator fx-155 es natural display

I am not sure what you want because the mathIO mode IS THE ONE THAT DISPLAYS results as fractions.
You have two display modes: MthIO (with fractions, radicals) and LineIO (with decimals). Which one do you want?
To set MthIO press [Shift][MODE][1:MthIO]
To set LineIO, press [SHIFT][MODE][2:LineIO]

Concerning the scientific display mode.
Decimal numbers can be displayed in various formats, Fixed,Scientific, and Normal. If you do not want scientific display of results, just set the mode to Fix(ed) and specify the number of decimal digits. However if a number to be displayed (a result) is too small or too large IT WILL BE DISPLAYED in scientific format regardless of the mode you selected.
