Is it possible to enter fractions in my new casio fx9750gii. ive tried the shift f-d key but it doesn't want to play


The F-D key converts from fraction to decimal and vice versa. The key to the left of the F-F key, and which is marked a b/c is the one used to enter fractions. The SHIFT F-D sequence toggles between improper fraction and mixed number. The OS of this calculator does not allow the displaying of stacked fractions.

How to turn off calculator


Most calculators have a key sequence to turn off power. The key may be dedicated (one function) or it can be activated by pressing SHIFT or 2nd first. For a Casio scientific calculator, press SHIFT followed by AC (All clear). Some solar powered calculators do not have a key to power off but the calculator will turn itself OFF after a moment of inactivity.

I want to calculate powers on my calculator but am unsure what buttons to press


You have two buttons to calculate powers: The [x^2] calculates the square of a number while the [caret ^] key allows you to calculate any power, be it with integer, fraction or negative exponent.
Both keys are next to one another, one below OPTN and the other below the VARS key.
To calculate roots, you have the square root [SHIFT][x^2] the xroot key [SHIFT] [caret ^] , the CUBE root [SHIFT] [(] , and the inverse key [SHIFT][).

TI 83 plus calculator has dim screen.


TI calculators have an annoying habit of dimming the screen when the batteries are changed. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

How can i get the shift of sine, cosine, and tangent in my calculator?


I am not sure what you mean, because your question already shows what you have to do.
To use the functions marked on the body of the calculator you use either the SHIFT key for the ALPHA key.
If a key has next to it (on the body of the calculator) two markings, the one on the left is accessed with SHIFT, and the one on the right with ALPHA. Colors of commands on calculator body are coordinated with the colors of the Shift key and the ALPHA key.

The question I am asking is whether you know what [SHIFT][COS] means. You probably do, but just in case you do not (no reflexion on your abilities)
[SHIFT] [COS] gives access to the arc cosine function, [SHIFT][SIN] the arc sine function, and [SHIFT][TAN] the arctangent.

The word "off" is above the red button AC. I press it, nothing happens-a cursor keeps flashing and the figure 0. is showing


If you want the All Clear function, press the AC key. If you want to turn the calculator off, press SHIFT then AC. The functions marked above the keys are the shifted functions of that key.

How to use the exponent key on a casio fx 300ES calculator ?


The key to use for the square, and the cube are well marked and they share the same physical key (X to 2) or [SHIFT][X to 2]. Similarly the keys to use for the square root and the cube root share the same physical location (the square root key, to the right of the square key).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).
  1. You enter the base (the number to be raised to a power).
  2. You press the [X to ] power key.
  3. You close the parenthesis (the right one).
  4. You press [=]
Sometimes the result may not be displayed as a decimal number, but as a radical (if you take a root). To make sure it is displayed as a decimal number, in step 4 above, press [SHIFT][=]

I am getting the wrong results when performing some basic FV math problems. Doy you have any math problems that would help test my calculator?


It might be more efficient to make the calculator perform a self-test. Here is the procedure.

Verifying Proper Operation (Self-Tests)

If it appears that the calculator will not turn on or otherwise is not operating properly, use one of the following procedures.

1. With the calculator off, hold down the [ON] key and press [X] (the multiply key)..
2. Release the [ON] key, then release the [X] key. This initiates a complete test of the calculator’s electronic circuitry. If everything is working correctly, within about 25 seconds (during which the word RUNNING the display should show –8,8,8,8,8,8,8,8,8,8, and all of the status indicators (except the * battery power indicator) should turn on. If the display shows Error 9, goes blank, or otherwise does not show the proper result, the calculator requires service.

Tests of the calculator’s electronics are also performed if the [+] key or the [divide] key is held down when [ON] is released. These tests are included in the calculator to be used in verifying that it is operating properly during manufacturing and service.

If you had suspected that the calculator was not working properly but the proper display was obtained in step 2, it is likely that you made an error in operating the calculator. We suggest you reread the section in this handbook applicable to your calculation — including, if appropriate, appendix A.

If it needs repairs, contact FixThatcal.org
Here are some examples from the manual (there is overlapping in the first two screen captures)

Division isnt working it just turns it into a fractio term EX: 1427 divded by 38..... casio= 1427 ----- 38


Sorry, but the calculator is working as it should. Read on till the end, you will understand how to use it to suit your needs,

If you do not want to see fractions and radicals ( roots) anymore just set the calculator Input/Output mode to LineIO:
Press [SHIFT][MODE](SETUP) and select [2:LineIO].

If, however, you appreciate the functionalities of the MathIO that allow you to manipulate fractions, radicals, and other nifty things you could not do before, but just want your final results to be in decimal format that can be arranged too.
Here is how
  1. Set the I/O mode to MtahIO: Press [SHIFT][MODE][1:MthIO]
  2. Enter your expressions, and when you are finished press [SHIFT][=]. Your result will be in decimal format.
  3. Alternatively, you can calculate your result in MthIO and convert the fractions/radicals to decimals by pressing the [S<=>D] key, the one located between the [)] and the [M+] keys.
  4. Every time you press that key you toggle the display from fractions/radicals to decimal and back.
