what's the difference between 83 and 83+? I'm going to guess that the one that's here already is an 83.. did promise to buy another one, if/when I found a deal (son is using daughter's, she'd like it back..).

 
From what I've noticed, the only difference between the 83 and 83+ is that the 83+ has more memory for games... or other things... Algebra thru Pre-Calculus there wasn't anything I couldn't do on my 83 that others could do on their 83+ or above.
 
The 83+ NEW version (there are actually four versions of the 83 - the 83, 83+, 83+ w/flash memory, and 83+ Silver) has flash memory. Other than that, I don't think there are any new features. The version for sale here is the one with flash memory. The one I have is the 83+ without flash memory, and it works fine.
 
Yep the 83+ just has more memory--not an issue if you never download programs to your calculator anyways. The silver also has a faster processor, the 83+ might be faster than the 83 also, but I don't quite recall.
 
yes the ti83+ does have more memory for GAMES.
This is a awesome deal. Just picked one up.
I remember purchasing the ti83+ for 100+ bucks..
thanks for the info guys.
 
For all you guys looking for calc for college, how about you just wait until college. All universities will push a different calculator, although the majority will push the TI's. My calc classes I to IV and beyond, 1 recommended HP's and the others used TI's. MOST WILL NOT ALLOW CALCULATORS IN CLASS, PROFS AT A MAJOR UNIVERSITY ARE NOT STUPID. An 83 is more than you will need for most apps and it's the safe way to go if for some reason you have to have the calculator in your hands 1/2 a year before you are starting college??? Then go and find a free version of Mathematica or most computer labs in your Engineering building will have it pre-loaded. An 86, 89 and whatever the new name of the new TI is would be nice, when you are broke 1/3 the way through the first semester, you will be kicking yourself when you could have saved the money on a more logical calculator. The only major I would push for getting an 86 or above is Mechanical Eng, other Eng classes you are fine with something less.

FREE VERSION OF MATHEMATICA?! WHERE????? That deserves to be posted in hot deals, since the student version and teacher versions (both are fully functional though) cost around $150.

Agreed, though, most good profs don't want you to have a calculator that does *all* of the work that they are expecting you to learn how to do... no more than your 2nd grade teacher would have allowed you to use a calculator for 5 times 6. (unfortunately, there are elementary teachers allowing kids to use calculators... but that's a rant for another time) Thus, a lot of profs draw a line somewhere... I think the most common line is after the 83+.

THANKS for this deal... I'm going to put a poster up in my classroom right now advertising this deal to my students... (and suggesting the pricematch at Staples, cince CC is over an hour away)
 
Man we are such nerds doing the whole calculator talk.
I personally own a 83+ Silver Edition, and 89.
 
It's been a while for me... does Staples B&M pricematch to free shipping deals (at the 110% rate?)
 
go for the 89 ... I am in Cal II in college and I had to switch from the 83 to an 89.

Didnt 'HAVE TO' but it makes life a whole lot easier
 
Great Deal! I tutor high school math as well as teach college level chemistry and this is the calculator that most students use. I have the old TI-81, so it is time to upgrade. I guess it is amazing I got through college level calc and diff. eq. with the 81 and an A, instead of an 89. I guess I just learned the material and didn't let the calculator do it for me. 😕

My high school Calc classes all STRONGLY recommended the 83 (this was when they FIRST came out).. I used my 83 all throughout Engineering Calculus 1, 2, and 3 (as well as the rest of my math classes) in college and it worked fine... Yes the higher models do the calculus for you but you can't use them in class so it's pointless to have it do it for you on homework and then be clueless on tests.
 
In my calculus classes in college, you aren't allowed a graphing calculator. you have to know how to do everything, and yes 83 is good enough, but 89 rock if you are allowed to use them.

it is only pointless if the teacher never taught the students how to derive and integrate, but there will come a time when integrating an equation will be too long, and as long as the teacher taught the students the basics of how to derive and integrate then it should be fine for students to move on and use calculators (although i do acknowledge with lack of practicing of integrating it'll eventually slip out of your memory on how to do it).

if you're a Comp Sci major go ahead and buy the TI 89 for your calculus and physics classes, less than half you've learned will be involved in your field anyways hehehe (that's what i heard)
 
Just thought id give you guys some more info on the deal. I went to a B&M CC and they had it in stock for the $99 price, when i mentioned the web site, the staff was hesitate about my word, so someone went on the site to check it out on one of the in store kiosk. We both see it still listed for $49.95. So after he goes to see a manager for a few mins, he comes back to say something about check again on the site to see if it is a web only deal ( i know it isnt). 5 or so mins later he is back and says im all set!! 😀 so this is a YMMV type of situation.


As for PM to staples..... i tried that. According to what the Staples rep told me, when they do a PM to a online vendor, they also have to charge the next day shipping price of the competitor since she told me that next day shipping is standard on all Staples shipments. When we were mentioning the TI83+ order, she said they can match the CC price of the calculator though will have to charge me 29.00$ for next day shipping since that is CC's price for next day delivery.Needless to say,i just laughed at her and hung up. Anyone ever heard of them doing this?? i have not..... if so they ruined any business from me.
 
Just to toss in 2 cents: the 89 is the only one that does symbolic math (variable in, variable out for factoring, expansion, integrals, etc). The 83 and 86 don't do that. The 86's interface is way too clunky IMHO. Hard to use.

The 83+ is really good at this price, but the lack of symbolic math is very apparent. In fact, because of that, I think my $15 Casio scientific is almost as good. My casio can also do numerical derivs and integrals, formula plug and chug, quadratics, numerical algebra, pretty much everything the 83+ can do except for drawing pretty lines.

Unless you need a basic unit that can graph or you need to do AP stats, I don't think the 83+ is the best there is out there. I hang onto my 89 for symbolics and my casio for usual scientific computation. Of course, not all profs allow all calculators, so check before buying. The price is really nice though, so you could always buy one and ebay it if it doesn't suit you.

Oh and the TI graph link USB has a $15 rebate inside 🙂
 
83+ is nice. I used it my freshman year in college and did very well. I did not need any calculator to derive or integrate. Now that I have an 89, I forgot how to do intergration by parts...oh it killed me in teh beginning of differntial equations. That said, I barely use my 89. The only time i use it is on a test to check my answers, but even i am starting to see the limitations of that because you have to show your work. The only tim ethis year it was really useful was when i had a test of Laplace Transform.

What model Casio do you have ??? Mine only does integrals. I think my model is the fx-115W bought backi n Feb '99.

I've never used an 83+, but the 89 that I own does more stats than I've ever seen on another graphing calc. You can input a data set into an excel-like spreadsheet and extract from that mean, median, mode, stand. dev. I really couldn't tell you what else it does, I didn't recgonize the symbols.

/me CEG major.

PS 92+ > *
 
Does this calculator solve quadratics, yes I know you can do it graphically but numberically is much easier.
*edit* it does solve quadratics using a pre-programmed App
 
Heres a good rule to follow:

Non-engineering majors: TI-83

Engineering majors:
a. poor engineers: TI-89
b. rich engineers: TI-89 AND TI-83

Trust me, both will be useful.

Me---> poor electrical engineering senior, and I've been using the TI-83 for 4+ yrs. If I had the money, I'd buy the 89 too, but the 83 is more than enough.
IF I had to choose (and I have used both), I'd probably pick the 83, its more user friendly and straight forward to use. My .02.
 
I have only used the 83+ on a regular basis and have found it pleasant to take AP stats and more than enough for what a teacher wants you to actuallly use a calculator for... But TI basic just sucks something awful. If you want to program anything complicated your stuck with using assembly. blegh. I haven't used a TI 89 for anything really, but I have been told that you can program it in C. Also, if you care, the 89 has more pixels and does gray better than the 83s IIRC. There is something to be said for the dominance of the 83 though. You can tell how annoying it is when the guy next to you braggs about his new calculator only to spend the next 10 minutes trying to find where the button that the teachers shows on an 83 is on his 89.
