Question about Casio FX-115ES Scientific Calculator

I get an answer of one.

To clear your calculator back to default, to the following:

shift

CLR (the button 9)

3 (select option 3 = All

= (the equal button)

AC (the red AC button)

Your calculator is now reset to factory settings

Now try your calculation.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

Try a reset SHIFT 9 (CLR) and reset 3:All

Also if Mode:1: COMP gives Complex, maybe MODE:2:CMPLX will give you the usual COMP mode. (wires may be crossed). I have a calculator that has two keys inverted. I made a note of it and keep it taped inside the sliding cover.

There must be an error in what you report. You pressed MODE then 4: Base-N and now your calculator is in base-N calculation mode (the DEC, Hex, BIN, OCT) numeration keys are active.

To do statistics you must put the calculator in STATS mode.

Press MODE: You have 6 computational modes to choose from

1: COMP, the general computational mode

2:CMPLX, for calculation s with complex numbers,

3: STAT for statistics,

4: Base-N, binary, octal, decimal, and hexadecimal numeration

5: Equation, solving mode, etc..

**For statistics, choose 3:STAT**

You're in BASE-N mode for integer arithmetic. Press MODE 1 to get to COMP mode for real arithmetic or MODE 2 for CMPLX mode for complex arithmetic.

You need to be in complex mode before you can do any calculations involving complex numbers. Press MODE 2 to switch to CMPLX mode. When you're done, press MODE 1 to switch back to COMP mode. (Yes, the names are confusing. I didn't pick them.)

It sounds like you need a manual for your calculator. You can download a scanned copy here, and it will explain what all the keys are for. For now, here is the way to set the calculator for a five decimal place display:

Spend some time reading the manual and work with the calculator. It's a powerful tool with a lot of capabilities. Thanks for using Fixya!

- Press the MODE key three times. A menu offering choices of FIX, SCI or NORM will appear.
- Press the 1 key to select FIX mode. The message "0~9?" will appear.
- Press the 5 key. This tells the calculator to display five digits after the decimal.

Press MODE 1 to select COMP mode (or MODE 2 for CMPLX).

Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.

You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).

set it up in correct rig mode, mode button (several times) until you get a window showing deg - rad - grad, choose deg (degree mode)

Sorry, but I think you misunderstood what the manual says. See the not on the screen capture.

True the sentence is not very clear, but what it means is the following:

All modes (except COMP) will have an indicator (with the appropriate labeling) displayed. When in COMP mode the COMP indicator is not displayed.

The truth of the matter is that computation- wise you have two MODES only : the general COMPutational mode and the Standard Deviation (SD Statistics) MODE. These two are incompatible because the key layout is different.

But to compute trig functions

But to compute trig functions

- calculator must not be in SD mode, hence it is in COMP mode
- An angle unit must be shown on display.
