<p>ticalc.org usually has a great selection :)</p>
<p>Thank you, il check it out.</p>
<p>I'm going into my second year and decided to upgrade to the 89, from the 83+. I found this guide, geared towards users with 83+ experience, helpful: <a href="http://education.ti.com/us/product/tech/89/down/tips.html%5B/url%5D">http://education.ti.com/us/product/tech/89/down/tips.html</a></p>

<p>Thanks, guyute!</p>
<p>These ti-89's are pretty expensive.</p>
<p>lol</p>
<p>these do some pretty powerful things. that's why their so expensive. it's worth it, I say</p>
<p>Many profs don't allow calculators at all. They're nice to have, but don't become dependant on them...</p>
<p>83 to 83+ isnt really an upgrade, you gain no new features except extra storage space (I bet you didnt use it all before).</p>
<p>the calculators are expensive because they can charge that much more than because of what they can do. They have been producing the exact same calculators for many many years (internally the TI-84 is still the same thing as the 83) and have never lowered their prices even though there is no way it really costs that much. Its a captive audience form all of the 8th graders or whatever who have to have one.</p>
<p>TI calculators are much cheaper on ebay or the such</p>
<p>when i was in eighth grade, i had to make do with a TI-82 that was bought from a thrift store for $10.</p>

You really shouldn't need a graphing calculator in eighth grade. In fact, it may do more harm than good.</p>
<p>okrogius, they've started integrating graphing calc all the way from 5th grade onwards now. it's sad...really really sad.</p>
<p>i started with mine in 8th, but now when i think about it...we didnt need the calc at all.</p>
<p>Wow, fifth grade? The first time I saw a graphing calculator was in eighth grade where my algebra teacher decided that she wanted to at least let us see one, so we used them in class for a week. It was a dinky old TI-82, and I was sure that I'd never need even a tenth of what it could do. Fast foward almost six years, and I've probably used almost all of the functions that my TI-83+ can do, and I miss the TI-89 that I borrowed from my high school for AP Calc. If nothing else the pretty print funtion made the 89 worth it.</p>
<p>I got mine 10th grade starting with Algebra 2. Never needed them before.</p>
<p>Who said anything about using it? The only reason I needed one was because everybody else in my math class (Algebra I, i think) had one. You know, the same thing as with clothes and shoes and other middle school things. It's not as though I knew how to use the functions; all it was to me was a glorified scientific calculator. I didnt get my 89 until AP Calc and even then my teacher put restriction on when it could be used in class.</p>
<p>I started using graphing calcs in 7th grade honors math. My Algebra I teacher, who I consider the best math teacher I've ever had, banned them from his room and went against the curriculum by not using them at all. (He later went on to become an Asst. Principal, I might add).</p>
<p>Anyone ever use their calcs with the CBL devices? I remember doing that frequently in Chemistry.</p>
<p>We used those occasionally in physics, in chem for doing titrations (on days when the actual ph meters were being used by other classes).</p>
<p>I would have never needed one of these in 5th-8th grade.</p>
<p>just the basic calculator, that Blue TI was fine.</p>
<p>In 8th grade all we did was like fractions multiplication and devision and stuff like that.</p>
<p>i did the same exact math in the 5th-8th.</p>
<p>Maybe my school sucked, idk but we did the same stuff every year/</p>
<p>I first started seeing them in sixth grade, but I didn't get one until ninth grade. Even then, I still used a scientific calculator. It wasn't until tenth grade that I started using a graphing calculator.</p>
<p>If AP Calc didn't require a graphing calculator, I think it's entirely possible for someone to go through high school without needing a calculator, other than perhaps a four function one.</p>
<p>no, you'd need at least a scientific calculator to do logs.</p>
<p>log tables =)</p>
