Wont let me punch in numbers arrow pointing to the left

Press SHIFT MODE 6 then select the desired number of digits after the decimal point. Alternatively, press SHIFT MODE 7 then select the desired number of significant digits.

Let me give you a general recipe to familiarize yourself with any calculator, if you are averse to reading the manuals.
Most function will work in one of two ways.
1st way
Enter the number, then press the key,; the result is displayed.immediately.

Second way
Press the function key ( a left parenthesis may be displayed) enter the number (close the right parenthesis if there was a left one) press the = or EXE or ENTER keys.

Try the two ways described above to calculate the following values. The answers are given. Here log is he decimal logarithm and ln is the natural logarithm.


log(1)=0
ln(1)=0
ln(2)=0.693147181
log(2)=0.301029996
ln(100)=4.605170186

log(10)=1 (= number of zeros after the 1)
log(100)=2. (= number of zeros after the 1)
log(1000)=3 (number of zeros after the 1)
log(10000)=4 (number of zeros after the 1)

Press MODE. Use down-arrow to move to the "Display Digits" line, press right-arrow, and pick an appropriate display mode. The FIX settings will display that many digits to the right of the decimal point, while the FLOAT settings will suppress trailing zeros.

Press left-shift [DISP] 1 2.

left-shift is the yellow key below the EQN key.
DISP is the left arrow key.

left-shift [DISP] brings up the display menu, 1 selects FIX, and 2 specifies the number of decimal digits to the right of the radix point.

Press MODE to bring up the mode editor. Press down-arrow to go to the second line. Use left/right-arrows to highlight NORMAL. Press ENTER to select it, then 2ND [QUIT] to exit the mode editor.

Alternatively, you can select any other display format.

I am not quite sure what you mean by "OFF BY ONE-TWO POINTS".
If you have a problem of "precision" you can increase the number of digits that the calculator displays.

1. Press [MODE]
2. Use down arrow to highlight the line FLOAT 0 1 2 3 4 5 6 7 8 9
3. Use right arrow to move cursor to one of the numbers on the line and press [ENTER].
4. The number you will select will set the number of decimal digits displayed.

Keep in mind though that most of the "precision" one may be seeking is illusory.

When doing trigonometric calculations make sure the angle unit set in the calculator is the one your problem requires (deg, radian.)

Hello,
Press [MODE]. Use arrow down to go to second line Float. Use left arrow key to move cursor to a number other than zero and press [ENTER]. If you highlight 2 your results will have 2 decimal digits, but if 0 is highlighted all results will be integers (no decimals).
Hope it helps.

Hello,

Turn calculator. Use arrow to highlight the 2:Graph and Geometry application. Enter your function at the bottom of the screen. Use TAB to move focus on command line.
Press [ENTER] to graph.
While graph is drawn, press [menu] key. Select [5:Trace][1:Graph Trace] . An X appears on the graph screen. Use arrow to move cursor towards one of the zeros you see. At some point the calculator will pop up the label [zero]


Press [ENTER]


Use arrows to move the cursor near a second zero. When [zero] pop up text appears, press [ENTER]



The value of the secon zero is also displayed.

You can also the nSolve command

Use the nSolve( function available in main calculator application. Here some exemples of syntax

On the second command line, the small vertical segment after the right parenthesis is accessed by the key sequence [CTRL] [infinity, beta, degree] key, the one under [left arrow/clear].



Hope it helps.

I have the exact same problem (just happended recently) with my TI-5045 II after 25 years of good service. My solution? I just bought another model: Sharp EL-1801V at Stapels for about $31.00. To get the old one fixed will probably cost me $25.00-30.00 just to diagnose, plus shipping and parts and labor. And that assumes I can find a shop to do it, or that TI still stocks the part(s) gone bad. Same old problem with all technology.

Hello
The floating point number display (FIX) is set to zero decimal digits. All your. numbers with decimal parts are rounded.
Look for a key that says [FIX]. Press it and enter a number say3 If I guessed right (Sharp makes numerous calculators) your numbers will show 3 decimal digits.

If there is no such key look for a [MODE] Button. Press the button. If you have a new screen with differents choices look for Format, Float,
On some older calculators there is a table below the display. At the left of the table one finds MODE--> or -->MODE
If it says there Mode DEG:4 that means to have angles in degrees you enter [MODE][4].

I think I exhausted all possibilities. Without you model number, I cannot do more.

Hope it helps.
