MthIO is the default mode for the fx-115ES. If you want to switch to LineIO mode, press SHIFT MODE 2.

Internet explorer keeps freezing up

ry running IE without add-ons, All Programs, Accessories, then System tools, find IE no add-ons. If it runs OK in this mode then you'll know that it's an add-on problem. You'll need to find out which is the offending one by disabling a few at a time in normal mode.

Casio fx-300ES Calculator inputting fractions

The little L is the way to separate the numerator from the denominator. That is the old way of writing fractions. If you want the stacked representation, switch the display mode to MathIO.
Press Shift Mode to get to Settings, then enter the number corresponding to MathIO.

When i turn it on it always appear f(X)= and on the sop the letter R and the word Math and i don't know how to chage it back to the normal one

The R at the top of screen reminds you that angle unit is in Radians. The MATH says that the Input/Output mode is MathIO. In this IO mode, fractions are stacked (2levels) as in textbooks.. The R setting should not bother you unless you are doing trigonometry problems (in which case set the appropriate angle unit). The MathIO allows you to do exact calculations with fractions and radicals. Beside you can always convert fractions ad radicals to decimals.
As to the f(x)=, I believe you have changed the computational setting from COMP (usual) to TABLE. In table mode you supply a function and the calculator generates a table of values.
To recover the normal mode COMP, press MODE and select COMP (should be the choice 0:COMP).

I have a CA656 model calculator. First, how cann I get it to show teh full answer to my math problems in decimal form. It is rounding to a whole number. Next, how can I calculate sin 30? What steps...

  1. Press MODE 9 to shift into Normal display mode, or MODE 7 and enter the number of digits you want to see.
  2. sin 30 EXE. Be aware that the result depends on the angular mode. Most math problems are specified in radians, while your example sounds like it's in degrees. To select degrees, press MODE 4. To select radians, press MODE 5.
  3. 30 * sin 30 EXE. Everything in #2 above applies.

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.

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

Press SHIFT MATH 2 to switch to the LineIO mode. You won't see fractions then. However, if magnitude of the number is too large or too small, the calculator will switch to scientific notation in order to fit into the display.

Press [SHIFT][MODE][6:Fix] and press a numbetr between (0--9). The number you select will be the number of decimal places your results have.
However if a result is smaller than 0.001 it will be in scientific notation.

Hope it helps.
