I have an exam tomorrow so I really need answers quick. Also at the top of the screen there are the letters "M MAT D FIX Eng"
This is valid for the Casio FX-991W but I suspect it works for the FX-991 MS.
The Engineering Mode is ON so that all results use the Engineering display. When you divide 5 by 10 the result in engineering notation is 500 x10^-3 or 500 milli some unit, hence the little m after the 500. Other symbols you might have are k for kilo, or M for Millions, G for billions, mu for microns, etc.
In Engineering notation, the exponents are always (positive or negative) multiples of 3.
o recover the normal display, you must turn off the Engineering Mode.
Press the MODE button repeatedly until you reach the EngON EngOFF page. Select 2:EngOFF.

Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.
Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.
Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.
Hope it helps.
