Hello,
I am not sure what the cross (x) means: is it a multiplication or the variable x, so I took a screen capture of both cases.

The top case is obtained as follows the asterisk is the multiplication sign to thr right of digit 9; the small minus is the change sign key the minus sign in parentheses under digit 3 and to the left of ENTER key.; the forward slash is the division sign, above the multiplication sign.
This small minus called change sign makes a positive number negative and a negative number positive, hence its name. If your expression starts with a negative sign that is the one to use. Use it also for negative exponents.

As you can see the result is -.8. Notice how the - before the dot is small with respect to the regular minus, as in the last expression.

For the last expression on the screen capture, there is nothing special, except that you have two ways to enter the variable X.

1. Press [ALPHA] [STO->]
2. Press the key [X,T, Theta, n] to the right of the green [ALPHA] key.

Hope it helps.

If x is the multiplication sign
8[x] [(] (-)1

There is no such thing as a TI89 Plus Silver Edition.

If you mean the TI-89 or TI-89 Titanium, press diamond / (the diamond key below the 2ND key, then the divide key).

If you mean the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition, press MATH left-arrow 4 .

Yes, you can change the faceplate of the TI 84PLUS Silver Edition only, not the TI 84 Plus. Face plates are available for purchase at the TI online store.When you go the online store, select the country, then the calculator model. You will find them under accessories for the TI 84 Plus SE.

### I can't graph on my ti-84 plus silv. edition

More than likely, you've put in a number in the xmin or xmax that is not correct. Example....you put in an xmin of 10 and an xmax of -10 which would be backwards. This could also happen in the ymin or y max.

The easiest way to fix this is to press zoom 6 which wil get you back to the default graph of xmin of -10, xmax of 10 and ymin of -10 and y max of 10.

If you can't see your graph on this screen and need to change the window, just be sure the number in the min for both x & y is smaller than the number in the max. You change your window size by pressing the window button.

### Comma key on TI-84 Plus Siver Edition calculator.

The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is.
