<p>I'm leaning towards 83 since it's 20 dollars cheaper, but I've been told that 84 has a lot of useful apps for BC Calc. I''m not planning on taking more math after AB BC and STAT. 83 or 84? (or 89, but since it's not allowed on ACT I'm not favoring it)</p>
<p>83+ should be fine. 84 really only has more memory, and when you talk about cool apps you can just download them from online. And I can’t think of any app you would need. All I did for calc was program some stuff for the Riemann sums section.</p>
<p>83+. I personally have an 89, but I kind of hate it. It’s like learning how to use a calculator all over again.</p>
<p>Any graphing calculator should be fine.</p>
<p>Used 89. Sell back when not needed. (Ebay because you can get even a new 89 cheaper than what you can get an 83/84 from the store)</p>
<p>I just hate saying get a 83/84. I’m like a Ti-89 salesman. 89 because it’ll kill your Calculus class. Computer Algebra System. It’s really hard to put what I’m saying into words–the 89 is simply much better when it comes to Calculus.</p>
<p>As for calculators, I hate 84s and a CAS CX is meh. I don’t know how to use them! But I’m sure I’d love the CAS CX if it was my first calculator, and as for the 84 I’d have to say I would’ve abandoned it if I got the 89 afterward. The only problem I have with the 89 is that it takes some of the satisfaction away at beating people in Calculus. The thought that maybe I do better because I have an 89 despite knowing how to do the problems anyways.</p>
<p>^ I second that. I would 100% recommend TI-89 for Calculus.</p>
<p>I say 83 because
- as u said its cheaper
- i have it for calculus and it works just fine
- u can download any app on there just like all the other calcs but this ones cheaper
and everyone says get the 89 but than u cant use it on the ACT so why waste your money on that to than have to get another calculater for the ACT …</p>
<p>and either way u have 3 options 89 83 or 84
89 should be out cause theres no ACT on there
and the 83 nd 84 are semi pretty close to being the same in my opinon but the 83 is cheaper … so i think the decision is obvious … but IMO atleast</p>
<p>who’s hating on the 84? :(</p>
<p>I <3 my 84. User interface is very friendly, since you can just type something in and it’ll spit out an answer. You don’t even need paired paretheses (i.e. you can type “3*(4+3” and it’ll give you 21). A lot of the menus are also really easy to access. The programming language (imo) is easier to understand.</p>
<p>I agree that the 89 is much more sophisticated with its computer algebra system and other stuff. I’ve used an 89 before, but there is NO function for calc class that an 89 has but 84 doesn’t have. Sure, idk if an 89 can calculate a double integral for you…but in that case I would prefer just to use Wolframalpha.</p>
<p>And going off ebay price. I guarantee you a new 84+ silver will be cheaper than a new 89 titanium at the same location.</p>
<p>I’m leaning towards 83+. Is there any app at all that is useful for Calc BC that I can’t get on the 83+ but on the 84/89? Unless there is, I’m going for 83+. I’m not a huge math person anyway, so a lot of the 89’s features seem unnecessary.</p>
<p>A TI-83 or 84 is sufficient enough, especially if you don’t want to spend a lot of money. However the user interface on the TI-NSpire/CAS/CX and TI-89’s are a whole lot better, plus the resolution is around 9x higher. I used an NSpire throughout AB, BC, and AP Stats.</p>
<p>I’m using 84 right now and it’s basically no different from the 83.</p>
<p>Ti- nspire CX is a step above the 84. It has many calc bc programs. The Nspire CX is ACT,BI,AP and SAT friendly. The extra cost is worth it. because, i hate to say it but, the 84 was good but is now out of date. </p>

<p>Is there any difference between 83 and 83+? They both seem to be ~60$ total on amazon</p>
<p>@Themost, the CX is definitely a step above the 84. We’re talking about graphing 3D functions!</p>
<p>However, for AB and BC, it might not be worth an extra $50 or $60. An extra $10, sure. However if you wish to pursue more advanced courses (multi-variable calculus, linear algebra, real analysis, topology), an NSpire CAS or CX can be worth it.</p>
<p>where do you get the programs to program into the calculator, and how do you do it</p>
<p>You just have to understand TIBASIC (which is a ridiculously simple programming language) to program stuff onto your calculator. Go to Prgm → New (or whatever) and start typing. You can use If, For, While, Repeat, etc. and colons mean new lines. I’ve programmed stuff like Snake on the graph and a system of linear equations solver (using matrices). If you search online you can find a whole lot of stuff; like, I think someone programmed the entire Pokemon Red or something. You can download the program using TIConnect and the link cable to your computer.</p>
<p>I have a TI-84 Plus Silver Edition currently. I want to do advanced maths, going into MV Calc, Diff Eq, Linear Algebra, Adv. Stat, and others. SHould i upgrade?</p>
<p>Getting a TI-89 will definitely be worth it, as it’s a calculator that can carry on to college-level math classes, not to mention that it has tons of useful functions that the TI-83/84 series lack.</p>
<p>I think almost all math kids across America have thr ti84 plus silver. It’s so awesomee haha </p>
