<p>I need to get a calculator and I wanted to know are there any calculators that aren't acceptable in classes? I'm thinking about getting the new TI-Nspire CAS that's coming out, or the TI-89 titanium.</p>
<p>Get an 89 =D</p>
<p>I hear a lot of classes don't even let you use em on tests though.......</p>
<p>Depends what kind of classes you see yourself taking. I feel like most people have an 83 from high school, and that's more than adequate to get by. Plus, julyinoh is right, most classes won't let you use them on tests or exams, so if that's the only reason you're trying to get the fanciest thing out there you might want to reconsider. That being said, and again depending on the classes you plan to take, a calculator that simplifies multi-variable equations and solves derivatives MIGHT come in handy on some homeworks.</p>
<p>For math classes beyond 53 (and this includes 50H), any calculator is next to useless.</p>
<p>Like docketgold said, it really depends on what classes you'll be taking.</p>
<p>Calculators can be nice in physics if you're lazy. But you can always just use Mathematica instead. What classes do you plan on taking? Or might you take? I agree that after Math 53, a calculator won't do you much good anymore.</p>
<p>Thanks for the advice. I've been using an 89 for the last two years, but it was stolen. I'm not sure which classes I'm taking this year, but it will probably be Math 51 or 51h and Chem 33 or 33x.</p>

Chem 33 or 33x

What do you mean? There is no 33x.</p>
<p>For the chem series, a scientific calculator is adequate, in my opinion.</p>
<p>sorry, i mean just chem 33</p>
<p>For those classes I would imagine any scientific calculator is fine. You'll find that the classes for which a calculator is most useful are the ones which aren't centered around math directly, economics for example. In these kind of courses (usually upper division ones), they just sort of assume you know how to do the math involved, and although it usually isn't difficult anyway and you'll need to be able to do it by hand on the test, a calculator can reduce the time it takes to do problem sets, if only marginally.</p>
<p>what type of calculator would you reccommend for upper-level econ classes (especially for someone who is pretty addicted to calculators for homework help)?</p>
<p>As an Econ major, I can say that you will be fine with an 83. Some might say that having an 89 is nice because it will derive and simplify complicated equations for you, but in my experience I've found that when the prof wants to give you a complicated, mathematical problem, you are going to HAVE to do it by hand and using a calculator in that instance just complicates things even further. Generally, homework problems will involve lots of variables rather than numbers, so you're going to have to learn how to do the correct derivations by hand. On tests, exams and the like, they won't even let you use a calculator of any sort. Thus, overall, I'd say stick with whatever you have used throughout high school. You're really going to want to break the habit of doing everything with a calculator or the exams will come as a big shock.</p>
