When is a TI-89 ever needed/useful?

<p>I made a program that multiplies polynomials of any degree or length and a factoring program, but most of my programs are useless (but fun lol).</p>

<p>My favorite program was a guessing “game” that asked you to type in a number, then told you it was wrong, asked you to pick another number and basically cycled through that.</p>

<p>Ooooh close, try again
Not quite, try again</p>

<p>My brother actually wrote a real guessing game somehow on his old Casio.</p>

<p>I’ve got wack a mole, hangman, wheel of fortune, blackjack, a program that adds one to every calculation for massive confusion. Making crazy 8s atm but the AI part is pretty hard, especially since I dont really play the game that often lol</p>

<p>TI-89 is hugely helpful in college. Probably not all that useful in high school, though.</p>

<p>I love how this thread has evolved. xD</p>

<p>Akabane I would love to know either the wheel of fortune or hero code</p>

<p>Ill post hero code, but u must know how to find these calc fnc on ur calculator!! (if u cant find a function, pm me). I highly recommend that u use an 84 or this program will be too slow to enjoy. </p>

<p>If u can’t find a function, click 2nd and then zero (catalog) to get a list of every fnc. click on A on ur calc to get to the As of the catalog, B for bs and so on.</p>

<p>If, then, else, output, clrhome are all under the program menu (click program button)</p>

<p>-> means the store function btw, which is the button above the ON button</p>

<p>code starts here</p>

<p>Find this later</p>

<p>I spent a lot of time posting this just so u know!! (my bday is coming up soon hint hint). Ill post this code on a second thread for ppl interested.</p>

<p>reposted code, some errors in last one lol</p>

<p>Controls for game (use right hand): pinky on enter, ring finger on minus sign, middle finger on divide, index on clear. Hold ur calculator sideways so that ur hand is in a position to flip some1 off (soz cant think of another way to describe hand position). Rock away!!</p>

<p>I forget. Is a calculator allowed on the AMC/AIME?</p>

<p>no and no .</p>

<p>If anyone is interested in raising their score on the SAT math section, you can also try the SAT Operating System. It is designed for TI-89 and TI-89 Titanium graphing calculators and enables the user to reduce the amount of time spent per problem while simultaneously increasing accuracy. It can be used during the actual test. To download the software, search twitter for ■■■■■■.</p>

<p>I used my calculator twice on the SAT math section. LOL, it’s a huge waste of time.</p>
