    I did everything you said but when I tried to reset the defaults it said "ERR: MEMORY" and "QUIT" so it didn't work. Thanks anyway.

My screen was frozen and I needed to do a manual reset. If you take out 1 battery from the back....hold the "del" key down and reinsert the battery while holding it down....it will reload the programming into the calc

First, turn it on. Once the calculator is on, press the "2ND" key (I believe it is a blue key in the ti-84 plus silver edition). Now press the plus key (+). A little above that key, you should see the word "mem." When you see the screen titled MEMORY, move the cursor all the way down to the option that says "Reset." From here, you can choose to reset either the RAM memory, or the factory settings. The factory settings are the "Defaults" option. I hope this helps.

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 .

Hello where is the fraction button on the ti-84 plus silver edition


There isn't one. If you want to convert a value from decimal to fraction, use the >Frac function (press MATH 1). If you want to enter a fraction, simply enter the numerator, divide, then the denominator.

For example, to calculate 1/4 + 1/3, press
( 1 / 4 ) + ( 1 / 3 ) MATH 1 ENTER
and you'll see 7/12.

How to simplify the equations in ti 84 ??


You cannot do it with this calculator. It does not have a Computer Algebra System (CAS). Try a TI89 Titanium, a TI 92PLUS, a TI 200PLT or a TI-Nspire CAS.
However, they may exist other programs on education.ti.com or ticalc.org. Search these sites and you may be lucky.
