    The flashing asterisk is the low battery indicator.

    Negative payments indicate outgoing. Positive payments indicate incoming.

The flashing asterisk is the low battery warning.

Press f 4 to see four digits.

Payments with a negative sign indicate payments you make. Payments with positive values indicate payments you receive.

Use a ten by ten grid to express the fraction 11/12 s a percent


11/12 = 0.916666. This number is infinite. So, you need to round it off to either 0.9167 or 0.917. of 1.0 whole number.

So as a 1/10th grid, the grid lines would be marked: 0.0. 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 The grid line would go (Rounded off) 2/100's (0.02) past 0.9. Divide the space between 0.9 into 100ths. 4 equal spaces. Label these spaces 0.02, 0.04, 0.06, 0.08 Your gridline will go from 0.0 to 0.9 to 0.02.

Flashing asterisk, BOTTOM left corner.


That's the low battery indicator.

Pull the batteries out, wipe them clean, wipe the battery contacts clean, and try again. Swap the positions of the batteries. Try the old batteries again. If you have another set of batteries, try them.

How can I change the setting to print total the decimals. It is rounded off to the nearest one hundred.


You need to set your decimal selection to full-floating if you expect any numbers to be more than 4 decimal places.

Each time you press the DEC key it changes the decimal selection. From F to 0, 2, 3, 4 and A in that order. F is "full floating" but appears as a blank on the screen. A is the "add-mode" for currency transactions. The "A" does show on the screen if this is your selection.

As soon as the letter for the number of decimal places you want ("F" is blank just before 0 decimals) appears on the screen you are "ready to go." Problem is, the decimal indicator numbers and letters are so tiny and screen is so difficult to read that under many lighting conditions your selections might be all but invisible. They are in the upper left side of the screen just to the right of the equally difficult to see multiplication and division rounding indicator "5/4." PS If the 5/4 does not appear on your screen then you have set the round-off function to not available.

I cant get a anser it comes out in scientific notation


Press [SHIFT][MODE] to enter the (SETUP) screen, then select the number to the left of FIX. Once you do you will be prompted to enter a number between 0 and 9. If you enter 4 all your decimal results will have 4 decimal digits. If you choose 0, all decimal numbers will be rounded to the nearest integer (whole number).

Regardless of the floating display mode (SCI, FIX or NORM) the calculator is configured for, the decimal results will be in SCIENTIFIC format if they are too small or too large.

Everytime I put decimals into my calculator, it just rounds the answer to the nearest whole number.


Increase the number of decimal digits in display.
  1. Press [SHIFT][MODE] to access the {SETUP)
  2. Enter the number (6) corresponding to option [6:FIX]
  3. In screen that is displyaed, enter the number of decimal digits you want (2, 3, or 4). If you enter 0, all decimal numbers will be displayed as integers (rounded). If you enter 9, you will have long numbers but that is hardly ever necessary.

How do I ente 8x - 1 over 10 on my TI 84 plus silve edition


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.
