If you cannot see anything on the screen, you may need to adjust the graphing TI 84 calculator contrast :

1. To darken the screen, press and release 2nd key, and then press and hold up-arrow key until the display is sufficiently dark.

2. To lighten the screen, press and release 2nd key, and then press and hold Down-arrow key until the display is sufficiently light.

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.

SOURCE: my TI-83 plus calculator doesn't work

As battery gets drained, the screen contrast dims. But when you change batteries, some times the contrast is reset to some low value and the screen appears dead: it is so light that you do not see anything, and you think the calculator is malfunctioning. This is the most frequent reason users think the calculator refuses to turn ON. And I hope that is the case now.
To correct that, you must increase screen contrast: draken the screen a bit. To do so

  1. press [2nd] key and release it.
  2. Press the Up arrow and HOLD pressure.
  3. Keep pressing the arrow key until screen is dark enough.
If that solve your problem that is good, rate the post accordingly.. If that does not, do not get irate and berate the post. Post a comment here describing what you did and what message (if any) calculator returned, and I will give you further diagnostic steps.

SOURCE: how to restore applications on TI-84 Plus Calculator

Go onto www.education.ti.com, find the downloads column, and click on apps and operating systems. Then you can click on the different lists and find out which apps you accidentally deleted. You do this by (after clicking on it) looking under the "Pre-Loaded On" column. If you find the name of your calculator there, this is one application that was deleted. Hope this helps!

2c + 6 + 7c = 8


To solve this with a ti-84 press [math] and select solve from the menu. This will open the equation solver. Type in your equation
(Note: you may need to put it in the form with 0=, So the equation would be 0 = 2c + 6 +7c - 8 ). Then press
enter or arrow down button.

How do you enter the "plus or minus" sign into the y= of a ti-84


The calculator cannot handle "plus or minus" in the same equation. If you need both, enter two equations into y=, one for plus and the other for minus.

Press the Y= button.

There are several possibilities:

1) Scroll through all equations, Y1 through Y9 and Y0. Make sure they are cleared.
2) The equation you typed in is not entered correctly.
3) Make sure Plot 1, Plot 2, and Plot 3 are NOT highlighted.

Deleted y column in TABLE


I do not think that you can DELETE it, you probably just cleared the equation, just put another equation into Y=, and it will work.

otherwise, if you don't have any programs you need or so... just press 2nd +

Scroll down to reset, and press clear RAM

Entering inequalities into TI-84 to graph


I think you should get a Texas Instruments calculator and push the 'y=' button then put the equation like '2x+4' in the y1 area. You can put the X by using the variable botton. I hope my english makes sense I am not a native speaker.
