Question about Sharp EL-2196BL Calculator

Setting features on calculator

How do I clear each individual equation when I am not using the paper roll? I only see a "CE" key but not a "C" key like I am use to. When I use the paper roll I use "*" key to clear.

I also want to set the tax to 7.75% but I am not having any luck. I go to "rate set" key in 7.75% and then go back to GT am I missing a step between the setting and GT?

Yes, you are missing a step. You need to first fo to rate set then enter 7.75% then hit TAX+ key. You may now go back to GT and it will equate tax.

How do i feed the paper of the casio fr 2500 printing calculator


Hello Michel Dekock,

Could not find your FR2500 (but close)...

Has worked every time for me...

Mount the paper roll on the wire bracket... feeding
over the top of the ROLL (TOWARD THE MACHINE).

With the keyboard FACING away from yourself
Fold the FRONT EDGE of the PAPER on to the
side to form a chisel point... and insert the point
(folded side up) in the rear roller slot (paper feed)...

As shown on FR2650
http://www.ebay.com/itm/Casio-FR2650TM-Printing-Calculator-FR2650TM-/122298781152?hash=item1c79934de0:g:bwEAAOSw44BYbWjv

With the PRINT feature turned on the roll should be
advancing while holding down the TOTAL key...

Hold the key until the edge of the paper roll emerges from the machine.

Hope that helps.
(now you only have to freshen up the ink).

Texas 30XIIB binomial cdf


The only known equation for the cumulative binomial distribution is the sum of the individual binomial probabilities. Some more sophisticated (and more expensive) calculators have that equation built in, but the 30xii does not.

If n>30 and n*p>5 and n*(1-p)>5 then you can approximate the cumulative binomial with the normal probability function, but again the 30xii does not have that built in.

CE button doesn't clear on my SHARP EL-2630PIII


CE stands for Clear Entry. It clears the number that one just entered. To clear the results of a previous calculation use the key AC, if calculator has one. Otherwise try pressing the CE key twice or enter 0, because that is what the clear button will do.

How do i calculate my rational equations using my casio fx-115es for example x/8=8/x


You do not need a calculator for this proportion.
For a proportion a/b=c/d, the product of the extrems (a*d) is equal to the product of the means (b*c).
In your case x*x=8*8 or x^2=64.
The two solutions are x=+square root (64) or x=-square root(64).

For a less trivial equation, you can use the solve feature of the FX-119ES. To do so, use the ALPHA keyboard to enter your equation; once the equation is typed in, do not press the main equal sign, but the Solve key (the key is located near the top left corner of the keyboard). You will be prompted to solve for X?.

My calculator is always in the scientific mode, i want it to be in normal mode, how?


Hi nolski,
Have a nice day.
Listed below are the ways to set your calculator from scientific to normal mode. 1.Clear your calculator of the last equation you did by pressing the "Clear" button. 2.Click the "Mode" button and use the arrow keys to scroll over "Normal" mode. This will set the calculator up to do basic equations versus any long algebraic equations, or other types of equations on which your were previously working. 3.Practice setting the mode to normal when your are done using your calculator so you always know what mode the calculator will be on when you turn it on next time.

How to do equations the papers that come with it doesn't explain it very well. Is there someplace where I can get a better explaination?


You can solve equations two ways: The EQN computational mode or the SOLVE application.
IN the EQN mode you can solve linear equations in one, two and three unknowns; the quadratic equation; and the cubic equation.
Enter the EQN mode by following the instructions on the following screen capture. Press 5:EQN
6_25_2011_1_06_32_pm.jpg
You have three types of equations.
6_25_2011_1_08_15_pm.jpg
Once you select the type of equations, a template is displayed where you enter the relevant coefficients.

6_25_2011_1_10_10_pm.jpg
Under each label (a, b, etc. ) enter a coefficient and press ENTER to move to the next. With a cubic equation, or a linear equation in 3 unknowns, you have to use the Right arrow to display the cells where you enter the value of d.
After you input all necessary coefficients press the = sign to get the solution.

To use the SOLVE feature, see the screen capture that follows. It comes from the Casio manual.

The top half of my screen split into four "windows." I can't get it to go away, no matter what I do. I can still do basic math equations at the bottom of the screen, however.


It is possoàible that you activated the split screen feature. IF THAT IS THE CASE, you can deactivate it.
  1. Press the MODE key.
  2. Use Down Arrow to move focus to the 8th (the bottom) line.
  3. Use the left or right arrow to highlight FULL, and press ENTER
  4. Press 2nd key then QUIT.
  5. Main screen will be whole again.
If that does not work, reset calculator to the Default configuration.
  • Press 2nd key then + to access MEMory management.
  • Select 7:Reset
  • Under RAM menu, select 2:Defaults
  • Press 2:Reset
  • Calculator returns with Defaults set.
  • Press the CLEAR key to clear the message.

So im asked to get the derivative of an equation, for example 2x^4+3x^2. I press home, f3, and input my equation, ,x and then press enter. instead of the solution coming out to be 8x^3+6x, the solution...


You have some numerical value stored in the variable x, which the calculator is plugging into the resultant equation.

You can clear individual variables with 2ND [VAR-LINK]. You can clear all one-character variables a-z with 2ND [F6] 1. You can initialize the machine for a new problem with 2ND [F6] 2.
