Scroll up After doing several calculations on my TI-84 plus silver edition, It wont scroll up so I can see my earlier calculations????

Use the TVM (Time Value of Money) solver. Press APPS 1 1. Fill in the known values, then scroll down to the item you want to solve for and press ALPHA ENTER.

All you have to do is to deactivate the MathPrint.

1. In Mode, scroll down to the second page of options.
2. Highlight Classic and press ENTER.

Press 2ND [MEM] 2 to bring up the memory management menu (MEM is on the + key). Select either All or APPS. Scroll down to the item to be unarchived. Press ENTER and the asterisk indicating that it is archived will turn off. If it is already unarchived, pressing ENTER will turn on the asterisk, indicating that is now archived.

Hello,
To enter the inequation you split it into two inequalities

Graph is as follows

Use [2nd][CATALOG] to access the relaional operators less than or equal, greater than or equal, and the operator AND.
To access the inequality signs scroll upwards from abs( to reach the bottom of the catalog.
Note: You can use t as variable only in parametric graphs. Use x.
Hope it helps.

Hello,
Press the [APPS] button. Scroll down till you reach Spanish or Espanol. Select the app and press [ENTER]. You are given the choice of setting 1.Spanish or
2. English.
Press 2 then [Enter].
Hope it helps.

"2nd" + "log"

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

The easiest way to fix this is through the Apps menu. Hit the apps key, then scroll down until you see any language(espanol, Deutsch, etc.). It should give you the option of switching to either that language or restoring to English. I just tried this on a calculator that was set to German. I hit Apps and scrolled down until I recognized the option for Spanish, and it still worked. It let me switch back to English.
Hope this works for you.

You actually don't need to restore factory settings for this. I did it accidently and fixed it quickly.

Go to Stat > Edit...

Scroll over until at the bottom of the screen it asks for a name. Press 2nd > 1. L1 should appear, so now, just press enter.

Or just go to Stat > SetUpEditor...

You need to turn on Diagnostics:
[2nd] [0] to get "Catalog"
[x-1] to scroll down to the d words
scroll down a bit further until you see DiagnoticOn
[Enter]

You should get R2 and R next time you QuadReg.
