<p>I want to pass down my TI 84 to my younger bro and get a new calculator</p>
<p>Which should I get??</p>
<p>Or does anyone recommend a Sharp, Casio, or HP calculator??</p>
<p>You should get a TI-83+. The [signing</a> key has been cracked](<a href=“http://www.ticalc.org/archives/news/articles/14/145/145154.html]signing”>TI-83 Plus OS Signing Key Cracked - ticalc.org), so soon enough it will be possible to run all manner of software on the 83, including the CAS from the 89 & the Nspire.</p>
<p>Wouldn’t the Ti 83’s relatively slow processor render running many ti 89/nspire apps useless? ._.</p>
<p>I personally have a ti89, and love it. I heard the Nspire has a “testing mode” button, where an LED lights up, and locks you out of programs. Might want to do a little research on that.</p>
<p>Hmmm…
I have heard some issues with Nspire
anyone else?</p>
<p>
I’m sure the CAS would run just fine. I suppose some 3D stuff might run slower, but that’s about it.</p>
<p>89 definitely. I’ve had mine for three years, precal to cal BC, and it’s invaluable. Nspire is mainly for show.</p>
<p>
</p>
<p>I would just check before a test how long different things take just so that you don’t enter something and lose your calculator for 10 minutes.</p>
<p>My only comment, since I know nothing about the Nspire, is whether it’s allowed in tests. Some versions I think are considered small computers, not calculators.</p>
<p>Most tests will have the same policy for the Nspire and 89, though some might let you take the Nspire in if it has the 84 cover. I doubt there are many tests that allow you to take the 89 in but not the Nspire.</p>
<p>well, tests are not an issue cuz I’m planning to use it for college</p>
<p>Then it doesn’t really matter what type of calculator you get - you won’t use it much.</p>
<p>what will you be using this calculator for? im in college right now, and i rarely have a use for mine.</p>
<p>well, just to tell you what kind of person I am…
I am someone who programs apps in my TI 84 just for fun.
And I am someone who like to use a good amount of features in calculators
ex) When I do a dot product, I will actually create a matrix and get a determinant</p>
<p>but dot products aren’t solved by determinants…</p>
<p>I’d just get another 84+. They’re fast and reliable. This is after using many 83s, and owning both 84+ and 89. I’ve looked at the nSpire, and that seems to be a bloated mess that comes with neither the reliability of the 84+ or the roboustness of the 89.</p>
<p>Thing is, the 89 is more like a PDA and has a built in CAS, along with a nicer interface. The nSpire functions much more like a 84+.</p>
<p>Considering that you’re posting here, I’m assuming you’re going into college. As a tentative math major, my experience is that the more advanced you get, the less calculator you will need. In fact, ever since AP Calculus BC, I haven’t needed anything more than a scientific calculator (though, to be honest, I stuck with a 84+ since it is an awesome scientific calculator with lots of extras that I never use, like graphing). After getting done with multivariable and finishing all my physical science classes, I haven’t laid a finger on a calculator; not even a four-function calculator.</p>
<p>Thing is, calculators are for arithmetic, not for real math. Keep that in mind - a 84+ is cheap, rugged, and will do all that you will ever need to do, unless your are truly incompetent at math and remain that way.</p>
<p>Costco is selling the TI-89 for $79.99 right now. My daughter’s first year calc class required the TI-89. I think I paid $130 on sale and thought I got a good deal!</p>
<p>graphing calculators are so high school . . . get a copy of mathematica instead</p>
<p>
I agree with this. I got a TI-89 Titanium in high school, and have almost completely stopped using it in college. Mathematica is just amazing.</p>
<p>I got the n-Spire because I barely ever used TI calculators, and the experiences I had with TI calculators were horrible. I hated how other TI worked, they seemed totally backwards to me, but the n-Spire seemed more logical to me. That said, I would’ve never bought a TI if one of my teachers didn’t take issue with my totally awesome and superior HP graphing calculator.</p>
<p>I got the regular n-Spire because I wanted a calculator that I knew wouldn’t be an issue for my math teachers. The regular n-Spire has a keyboard that converts it to an 84+ Silver, which is usually what teachers do their demo’s with, and it hardly ever an issue on tests. It also has a testing mode that disables any user memory for both keyboards…but don’t use this unless you have access to another n-Spire to take your calculator out of testing mode. I found this out the hard way.</p>
<p>I would’ve preferred the CAS version, but I didn’t know my teachers wouldn’t care.</p>
<p>Supposedly the n-Spire is supposed to be the future for top end TI calculators, but it’s not ready for primetime yet. TI still needs to do a lot of programming to make it a full replacement for the 89.</p>
<p>I’m not all that happy with the n-Spire. Only somewhat recently did it become programmable. The battery life sucks. It’s slow. The little buttons are so high that I have a hard time using the regular buttons quickly and without accidentally hitting the little buttons. If it were faster, more conservative with the batteries, and had stiffer little buttons, I could probably be very satisfied.</p>
<p>I have had a Ti-89 sionce 8th grade, same one, this is the pre-Titanium Ti-89, and I find that it constantly outclasses my classmates non-Ti-89 calculators, which are brand new. That said, I don’t use it much.</p>
