I CANT GET MYCALCULATOR TO DO FRACTIONS CAN YOU HOPE ME


To configure the calculator to do fractions, set the Input/Output mode to MathIO.
Press [SHIFT][MODE] to open (SetUp) then select [1:MathIO].
After you set it to MathIO, pressing the fraction key will display a fraction template where you can enter numerator and denominator as you would by hand (horizontal fraction bar). Also, the calculator will display results as fractions and radicals whenever possible.
To perform arithmetic operations on fractions use the regular operation keys (x, +, -, /). The calculator will perform the operations and display the results as fractions (whenever possible).

This is so easy but I've forgotten. I have an old manual Casio caluculator. I just want to divide a series of numbers by 4. I can't seem to figure out how to do it. Any ideas? Thanks, Julia


If your calculator has the capabilities to do constant calculations here is how you perform calculations with a constant.

  1. Enter the constant (4)
  2. Press the operation key (/) once.
  3. Press the operation key (/) a second time.
  4. Your calculator may show a k in its display (LCD)
  5. To divide a number by 4, enter the number and press =
  6. To divide another number by the constant (4) , Enter the number and press =
  7. Keep entering the dividends and pressing =
I hope it works for you.

My calculator says DEG in the top right and I don't know how to remove it. Is this something that will not allow me to perform simple functions. Ten year-old children need to use this for class, so it...


The calculator has three angular modes: degrees, radians, and grads. No matter which of the three you select, the calculator will indicate which one it's in. You can get rid of the DEG, but only at the expense of getting one of the other two.

This should not affect the operation of the calculator in any way (except, of course, for the trignometric functions).

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.

Has new battery and wont turn on


Hello, You can try to perform the self-test. Procedure is as follows. To perform the self test on units with two batteries:
  1. Turn the calculator off.
  2. Press and hold the c01788482.jpg and c01774569.jpg keys; keep both keys held down for the next step.
  3. Press the c01788481.jpg key so the c01788483.jpg and c01788481.jpg keys are held down simultaneously.
  4. Release the c01788481.jpg key.
  5. Release the c01788482.jpg key, followed by the c01774569.jpg key. The main test screen displays the following: '1.L 2.C 3.H'.
    • Press c01788484.jpg to perform the LCD test (all LCD segments will be turned on). Press any key to exit.
    • Press c01788485.jpg to perform the checksum test and see the copyright messages. Press any key to go from one screen to the next until the main test screen, '1.L 2.C 3.H', is displayed again.
    • Press c01788486.jpg to perform the keyboard test. Press EVERY key on the keyboard until all the keys have been pressed at least once. The screen will progressively turn off with each key press. Once all the keys have been pressed and the screen is clear, press any key to return to the test screen.
Press c01788481.jpg to exit the test system. This will also turn the calculator off. If the calculator detects an error at any point, it will display an error message. For the HP 12c financial calculators with one battery, to perform the LCD self test:
  1. Turn the calculator off.
  2. Press and hold the c01788480.jpg key, and simultaneously press and hold the c01788481.jpg key.
  3. Release c01788481.jpg then c01788480.jpg .
  4. After a few moments, all elements of the screen should be displayed. Press any key to exit.

I just want to find out how to use the simple functions of my desk calculator, ie. add, and multiply in one operation and so on.


Usually you enter the first number then you press the key ( +, -, x or /) corresponding to the operation you want to perform and you press the equal sign (=).
ex: 15+3=18


Often you can perform the operations one after the other without bothering with the intermediate results. You can do so provided you respect the priority rules: parentheses,powers, multiplication/division, addition/subtaction...)

Hope it helps
