All calculator use scientific notation if the result is too small or too large. Some, like the Casio FX9750G II, offer you two Normal displays, Norm1 and Norm2 that have different limits when numbers are converted to scientific notations.

Here is how to set one or the other.

In Run>Mat press SHIFT MODE (Setup). Scroll down or up to reach the display line. Press F3 to select Norm1 or Norm2.

Press MODE then select "NORMAL" on the first line. Optionally, you can select the desired number of digits after the decimal point on the second line.

Be aware that if the magnitude of the result is too large or too small then the calculator will automatically switch to scientific notation no matter what settings you have.

Engineering notation ALWAYS puts the exponent as a multiple of three (kilo, mega, giga, etc). If you want the exponent as it is, use scientific notation. You can put the fx-115EX into scientific notation by pressing SHIFT MODE 7 and then entering the number of digits you want after the radix mark. Unfortunately there is no way to have the calculator adjust both the mantissa and exponent by anything other than three.

The "problem" is not how to calculate with numbers expressed in Scientific Notation but how to enter a number given to you in scientific notation. Once the number is entered you do not have to do anything special. If you have to multiply it use the (x) button. to add it use the + button, etc.

How to enter a number in scientific notation.

Type in the mantissa (example 6.022)

Press the [X10^x] at the bottom of keypad.

Enter the exponent (example 23)

with this example you will have entered Avogadro's number 6.022x10^23

Other example

1.6 [X10^x] (-) 19 enters the electron charge in Coulombs. The exponent is negative that is why you press the change sign key (-).

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.

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.
