In Casio Graphing calculators, MA error stands for Math Error. The calculation overflows the memory.

They're both giving you the same number.
1.953125E-03 means 1.953125 * 10^-3, which is 0.001953125 .

The fx-82MS does not have any built-in functions for calculating the normal probability distribution or its related values. You can calculate it using the defining function or any of a large number of approximations. Alternatively you can look up the values in a table.

Some advanced calculators have the functions built in, and programmable calculators can be programmed to give them. Sadly the fx-82MS is neither.

For more about the normal distribution, see http://en.wikipedia.org/wiki/Normal_distribution

Press SHIFT 9 To clear and reset defaults.
Or Press SHIFT MODE to enter (Setup). Look for option <CONT>. That changes the screen CONTRAST.

Sorry, the calculator does not have that capability.

The two calculators you are referring to do not have a financial utility. they cannot calculate cash flows. Casio does make a financial calculator, the FC-200V. Texas Instruments has two or three Business Analysts and so does HP. Some Casio Graphing Calculators are able to perform TVM, Amortization and such like financial applications.

Not all calculators have that. The Fx115ES and the FX991 ES have a lot more options thatn the FX300Es and FX350ES. I believe you only have COMP (general computational mode), Table and STAT.
Why? It was not designed that way.

Hi,

you should try the S=D button right above the DEL button.

Hello,

Find on the calculator the [nPr] key either (you may have to use the [2nd] or [2ndF] key) then
1. Enter the number that corresponds to n eg. 18
2. Press the [nPr] key
3. Enter the number that corresponds to r eg. 5

18[nPr]5 gives 1028160

If you calculate combinaitions use [nCr] key.

Hope it helps
