Braun ET55 buttons do not work

Does anyone know where I can get a Braun ET55 calculator repaired? The following buttons do not work: decimal point, plus, minus, M+, M-, MR. This is my favourite calculator which I used for many years. Since retiring, I've hardly used it which may be the problem, although it worked fine a few months ago.

SOURCE: how do i change the mode on my Casio fx-82au plus calculator?

Press SHIFT [MODE] to bring up the mode screen. Press 8 for NORM, then 2.
Bear in mind that if the magnitude of the number is too large or too small the calculator will switch to scientific notation anyway. For example, if a number has twenty leading zeros then it won't fit on the display unless it displays it as a power of ten to the negative twenty.

Need to change my display from a comma to decimal


I don't know which particular calculator model you have, but for an HP-12C, the manual says the following:
Digit Separators
As a number is keyed in, each group of three digits to the left of the decimal point is automatically separated in the display. When the calculator is first turned on after coming from the factory - or after Continuous Memory is reset - the decimal point in displayed numbers is a dot, and the separator between each group of three digits is a comma. If you wish, you can set the calculator to display
a comma for the decimal point and a dot for the three-digit separator. To do so, turn the calculator off, then press and hold down the [.] key while you press [ON]. Doing so again sets the calculator to use the original digit separators in the display.

I have a TI-83 plus calculator. I put into the calculator 96-5.970 ^2 multiplied by 0.2723 and it gave me the answer 2.4507 ^E- 4 Is there anyway to get the answer to the decimal value instead of it...


2.4507E-4 is scientific notation for 2.4507 times ten to the minus 4, or .00024507.

Take the 2.4507 and move the decimal point, to the left if the exponent is negative, to the right if it is positive, the specified number of positions.

If the magnitude of the result is too small or too large, the calculator will automatically switch to scientific notation. Imagine a number that has more than 12 digits to the left of the decimal point. How is that going to fit onto the display? Or a number that is 0 followed by the decimal point followed by 12 0s and then some significant digits?

"Fix" indicates the calculator is rounding results. Press "Fix" followed by "." (decimal point) to remove the fixed decimal setting.

Show two decimal places


Input the following and try:
  1. Press 2ndF and . the point button. This changes the screen to FIX DEG
  2. Press 2ndF +/- 2 Answer shown is to 2 dec. pl.
  3. If you want it to 5 decimal places, Press 2ndF +/- 5 answer shown is to 5 d.p. and so on
For normal, just take calculator out of FIX so just DEG shows.

Couldn't find you a YouTube video, so text will have to do.

There is a button in a vintage textbook showing a calculator with a "FIX" button. What was that button for?


Followed by a digit key, it probably set the display to fixed decimal notation with the specified number of digits following the decimal point.

No, it didn't magically fix a broken calculator :-)

I want two decimal points to show


I called Canon customer support. There is a tiny reset button on the lower back area of the calculator. Simply stick a small object in there to reset the calculator and you should be as good as new! Worked for me!
