Question about Texas Instruments TI-89 Calculator

I don´t know why, but it is very unconfortable, because on screen i can not see which number I type and the result either..

for example, i press the number "2", and then "enter" in the main screen appears <<..>>

the same thing for opperations like amounts, multiplication, etc..

Try resetting it... Will probably rid you of your problem.

2nd>Mem(+ sign)>reset> right 2c(ALL at top should be highlighted)>yes

You will need to reload all your programs, and while your at it you should probably update the OS from the TI site...

Good Luck

The selector you are asking about is the "decimal selector". The result displayed/printed, will be in a format according to the position that you have selected as follows:

f = floating (the result will be in the number of decimal places that were entered on the keyboard

4= fixed 4 decimal places (x.0000)

3= fixed 3 decimal places (x.000)

2= fixed 2 decimal places (x.00)

0= fixed 0 decimal places (x)

add 2= (add mode*,fixed 2 places) ($.00)

Note* "ad mode" automatically enters the decimal place when entering the number on the keyboard. If you enter "123", the displayed ammount will be "1.23". If you enter "1", the display will read ".01". This is a useful setting when adding a list of numbers in a dollars/cents format, however, be careful, if entering a whole dollar ammount "three dollars" be sure to enter the decimal point, or enter the number as "300". If you don't, the result will be ".03", instead of the 3 dollars you intended.

Adjust the screen contrast. Turn the calculator on. Press and release the 2nd key, then press and hold the up-arrow key until the numbers darken. If you go too far, repeat the process with the 2nd and down-arrow keys.

Instead of hitting the [table] button. You should hit the [stat] or
[stats] button as I forget which it is. Then hit [enter] which will
bring you to a stats list editor of some kind. You will want to enter
the data for your x-axis in L1 and the data for your y-axis in L2. Once
you have completed your lists, hit the [stat] button again and then
click [right] or the right arrow in order to move to the section of
calc. from number 4 down it will help create a graph of that type of
function. lets say you think it is linear, so you hit [enter] on number
4 and then you will be at the home screen with LinReg already written.
You just have to complete the statement and it will do it for you. hit
the [2nd] [1] and then the comma button, then [2nd] [2] and [enter].
that will do it for you.

Hello,

Between the x`squared key and the log key there is a key with an x with a raised small figure of a solid square. That is the key you use to enter arbitrary exponents.

- If calculator is in MathIO ( a Math indicator appears on the upper band of the screen), enter the base of the power (here 2). A number 2 with a raised empty square appears.The cursor will blink in the raised square. Enter there the exponent (here 12) and press [=]. Result 4096 appears at the bottom of the screen.
- If in LineIO (no Math indicator appears on the narrow band at the top of the screen), press 2 and then the key I talked about above. On the screen a number 2 appears with a hat and a left parenthesis. Type in the exponent (here 12) , the right parenthesis and press [=]. The calculator should display 4096.000...
