Testimonial: "Very much appreciated, quick response etc. "

change the mode to stat and then start operating it in statistical mode

In any scientific calculator log2(n) can be  calculated with either ln or log function as follows

Log2(n)= ln(n) / ln(2)

Or
Log2(n)=log(n) / log(2)

both will give nearly the same answers

This will show you how to do statistics (calculate average, standard deviation, regressions etc.) as to the mode and median refer to the definitions.

TO COMPUTE STANDARD DEVIATION AND 2-VAR STATISTICS.

I assume you know the theory. I will show you the key strokes

For 1-Var statistics
Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.
Enter a number and press [=]. Cursor jumps to second number to enter.
Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.
Press [AC] key to clear the screen.
Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.
Press the number corresponding to the statistical value you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.
To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics
To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. As I assumed above, you should be able to recognize what each variable means.

### Future value

The calculator does not have a TVM function/feature.

### What are step by step instructions for finding present value of 20%?

The first step would be to determine the rest of the problem. What's the future value? How long? Are there any payments? If so, how much and how often?

Asking for the present value of 20% is like asking "how do I get to the store?" Which store? From where? Are you driving, walking, riding a bike, or something else?

### Can this calculator do present and future value?

No, it does not. You will need a graphing calculator such as the Casio FX-9750G Plus or the newer version FX-9750 GII.

### How to calculate 17^23mod55 in casio scientific calculator fx-991MS?

Using the Windows calculator in scientific view, we get:
17^23 = 19,967,568,900,859,523,802,559,065,713
which is 29 digits long, ie much longer than the capacity of most calculators.

Because both 17 and 23 are prime numbers, it isn't possible to simplify this calculation, so you will need to use find a calculator that has sufficient capacity to be able to handle numbers of this length.

The xnumbers add-in for Microsoft Excel can also be useful for this sort of calculation (do an internet search for it).

Using the Windows calculator, MOD55 of the above number is 18.
