Which Calculator is good in general?

<p>So, I am thinking of purchasing a calculator. Is there any suggestions?</p>

<p>TI 89 will do anything you want it to and could make your life really easy especially in college…but it’s not allowed on some AP tests, I would go with TI 83 or 84 they’re both good deals</p>

<p>I am pretty sure that the TI-89 is allowed on all AP tests and SATs.</p>

<p>The TI-89 is only a little more expensive than the 84 if you know where to look and it is definitely worth it IMO.</p>
