Question about Texas Instruments TI-84 Plus Calculator

Open Question

My TI 84 stopped working

I was doing some basic addition and subtraction sums while i was doing some solidworks stuff. i did a couple calculations, got the number and put it into solidworks when i came back to the calculator it stopped working it just locked up on the screen it was on. Wouldn't let me turn it off or anything. I pulled all the AAA batteries out and turned it back on the cursor is just black and doesn't blink. I pulled the little backup battery out and it had the same effect. is there anything i can do?

SOURCE: TI-83 Plus silver edition won't turn on.

the screen may be at the lowest dim setting, try turning it on, then pressing the 2nd key and then hold the up key and see if anything appears, if not let me know and I will try to figure out something else, I own a 83, 84, and 89 so it shouldn't be too hard to figure out

SOURCE: how to restore applications on TI-84 Plus Calculator

Go onto www.education.ti.com, find the downloads column, and click on apps and operating systems. Then you can click on the different lists and find out which apps you accidentally deleted. You do this by (after clicking on it) looking under the "Pre-Loaded On" column. If you find the name of your calculator there, this is one application that was deleted. Hope this helps!

SOURCE: Can you Factor on a TI-84? IF not, does the TI-89?

Well, to answer part of your question, yes... the TI-89 does factor like this. it is inputted like this:

factor(6*x^2+11*x+4,x)

Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()

I have a TI-84 and when i put a negative number it appears Ans before how can change that?


Use the (-) key to the right of the decimal point key when entering a negative number. The - key to the right of the 6 key is for subtracting something from something else. In order to subtract from something, if you don't specify anything then the calculator uses the previous answer as designated by "Ans." The same thing happens with the + key for example, because it adds something to something else.

Is there a guide of how to use this calculator i do not under stand how to work this


Here's a link to a pdf of the manual. The basics are that you have 12 white keys near the bottom, which include the 10 digits, a decimal, and the negative sign. On the right, you have the four operating keys, division, multiplication, subtraction, and addition. You also have the Enter key which will solve the expression. You'll notice that the buttons have blue and green lettering above them, and those are for the 2nd and alphabet functions. So if you press the 2nd key on the top-left, then the on key in the bottom left, then it'll turn it off, because it also functions as the off key. The Alpha key is used to input letters which are in green above each number. Good luck!

When iam pressing the - sign it is not coming only - instead it is coming along with Ans and the - like this Ans- and the ans has some additional value in it which is creating problems in my calcuations....


The - key is for subtracting one value from another. If you press - at the beginning of a line, the calculator has to provide something to be subtracted from and thus provides the Ans. You'll notice that it does the same thing with +, for example.

If you want to enter a negative value, use the (-) key located just to the right of the decimal point key.

How do input subscripts into a program with a TI-84 Plus? Like Y(sub 1)=y


Use the square brackets ("[" and "]"). They're the shifted functions of the multiply and subtract keys. For Y(sub 1) enter it as "Y[1]".

I cant figure out how to be able to take a fraction and subtract it to another fraction on my TI-84 PLUS calculator


Given two fractions a over b and c over d, you can subtract the first from the second by entering
( c / d ) - ( a / b ) ENTER

The calculator will give you a decimal result, which you can (probably) convert back to a fraction by using the >Frac command. Press MATH 1 ENTER
