SOURCE: my ti 83 plus calculator wont go on


First of all, and I mean no offense here, check that the batteries are inserted correctly, respecting the polarity +-+-. The flat part (bottom) of the battery is the one that sits on the protruding helix-like electrical terminal. Inside calculator, there is polarity diagram.

When you change batteries, the display contrast may become too dim (too light) for the user to see anything. In that case, it can be adjusted.

Adjusting the screen contrast. Here is how to do it.
There is a key labeled 2nd. It is blue on the TI84Plus, and yellow/orange on the TI83Plus.

  1. Press the [2nd] key and release it.
  2. Press the [UpArrow] key (the top of the long vertical key in the Malta Cross like group of keys) and HOLD.
  3. On the top right corner of the screen you will see a number, which tells you the degree of contrast.
  4. Release the [UpArrow] key when contrast is adequate for your viewing.
  5. If you darken the screen too much, lighten it by the same procedure, pressing the [DownArrow].( See #1 and 2 above)
The lack of screen contrast is the most frequent cause of 'malfunction'. Try readjusting contrast, as described above. If that does not solve the problem, post a comment to this thread detailing what you did and the calculator response and we will troubleshoot further.

Good luck.

SOURCE: My TI 83 Plus won't work

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. 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.

I'm trying to find the fraction button on my texas instrument ti 83 plus calculator and cannot find it

There is no "fraction" button on the TI-83 plus. You will have to press the divide key (2 buttons below the CLEAR key) and then use the parentheses (immediately to the left of the divide key) to tell the calculator the correct order of operations. For example, "1/3x+9" means ".333333x+9", but "1/(3x)+9" means the "x" goes on the bottom of the fraction.
