Take the time to read the whole post. It explains the use of variables on the calculator. The use of the solve( function is at the end of the post.

The variables you have at your disposal in this calculator are
A, B,C,D,X,Y,M. All of them are accessed by pressing the [ALPHA] key before the key near which is written the name of the variable. You will notice that the markings of the symbols accessed with the [ALPHA] key are of the same color as that of the [ALPHA] key.
You will notice also that there are two = signs.
The one at the bottom right executes the command line. By pressing it you find the result of the expression just entered.

The other = sign is marked on the body of the calculator with the same color as the [ALPHA] key. It is located at the top left of the keyboard (excluding the row with SHIFT, MODE, the navigation buttons)

Example to enter X^2-2X-35=0 (not your expression)
Direct access physical keys are in [ ],
[ALPHA] (X) [X to power 2] [ - ] [2] [ * ][ALPHA][(X) [ - ] [3][5] [ALPHA] (=) [0]

Usually when you enter such an expression it is with the intention of solving it for X. By default X is taken to be the UNKNOWN. You will be prompted to enter the value assigned to any other letter symbol (Y, A,B,C,D).

So, if you want to use the Solve function, you press [SHIFT] [CALC] and the calculator will ask you a question: "Solve for X?" , and you press the = sign at the bottom right.
Then you will be prompted for any other non-X letter.

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 Referable 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.

How do you take the 3( square root) of 64 or the 4 root of any other number? im trying to take the 2nd button but still having trouble ? can u please help?


Hi shiny_diamon
Here is a picture of the powers and root functions of your calculator.
1.To calculate the cubic root of a number you use the key combination shown on line 5
Ex: Cubic root of 27
27 [2nd] [3 root x] [EXE]; Should get 3
2. You can use the general root key on line 7 [2nd][x Root y]
Ex: Cubic root of 125
125 [2nd][ x Root y] 3 [EXE] Should get 5
(-125) [2nd][x Root y] 3 [EXE]; Should get -5

3. You can also yse the general power key on line 6: [Y to x], but the degree of the root is entered as a fraction 1/3
Ex: cubic root of -125.
(-125) [Y to x]( 1/3) [EXE]; You should get -5

4. The [Y to x[ key is the one you use to obtain all other roots fourth, fift, tenth, n-th.
Ex: Fourth root of 256
256 [Y to x] (1/4) [EXE]: You should get 4

Hope that helps.
