<p>No way. On the 89 you don't need to remember the order to enter information like you do on the 89. The 89 also has some inverse features that the 83 doesn't. The 83 can't compare as a statistics calculator.</p>
<p>what features for stat does the 89 have? i'm just curious cuz i might be wrong...</p>
<p>With the 89 you have to download a statistics program to be able to have most of the features that the 83/84's already come with. Same for 86.
But if you do download the stats package, all are pretty much the same, even with the same syntax. There really isn't much of a difference besides 89's pretty print.</p>
<p>so i was right in saying the 83 is a better stat calculator... ;)</p>
<p>TI-89 Titanium...most powerful graphing calculator allowed on standardized tests, besides the ACT, 'cause they can't handle it...lol..TITANIUM</p>
