USED product received with no manual or USB cable. The listing does not state its used and photos show brand new product and packaging. Why would I purchase a used calculator for $125 when I can get a brand new one for the same price? Very disappointed and will be returning.

USED calculator sent instead of new as advertised

walmart.com

So I got the calculator that's being advertised which is great, but there's a few things that threw me off. First, I ordered it through Walmart and yet it came through Amazon, which I didn't know was a thing if it actually is. Second, I don't personally remember reading anything on the advertisement that the calculator was used because it has markings engraved into it with someone's last name, that was news to me thank you for that. Thirdly, the cable that is usually supposed to be with the calculator to sync information from a computer was not in the package, so that's also great. Overall, I got the calculator but in no way did it say that the calculator would be coming from Amazon.

Calculator Confusion

This calculator is not for high school math; however, it is a great help with calculus, linear algebra, and similar subjects. Although it is not allowed on tests in my college, it is very useful when practicing problems and checking work. Also, there are many applications that can be downloaded to it that are and are not math related; these provide extra functionality as well as entertainment (there are many games available).

Good for advanced mathematics

Amazing in every way. This is a GREAT tool for all different kinds of math and/or science classes (I use it currently in AP Calculus as well as AP Chemistry) and is much better than a generic scientific calculator due to it's advanced functions as well as "calculation memory" (you can see all of your previous calculations and use their answers as well, instead of just your most recent answer).

Definitely out-trumps the TI-84 and 83, as well. Walmart has the best prices and I'm glad I bought this!

Awesome!

Compaired to the TI-89 everything else is like an abacus, but it IS a little pricey! If you plan to do much programming, I reccomend you also get the black (win) or grey (mac) serial I/O cable ($20.00) and download the graphlink software from TI's website. The TI connect software doesn't let you write programs on the computer like graphlink does, and the USB cable that comes with the TI-89 isn't compatable with the graphlink software.

Excellent calculator

I love this calculator. I've used it through part of high school, and planned on using it in college. However! It is a CAS program. Computer Algebra System, meaning it will solve many problems for you, including, calculus. This is amazing for upper calculus, when you don't feel like thinking about the simple parts of a problem, but MANY teachers don't allow its use, which is kind of annoying. If you do buy this, ASK your teacher if it's allowed.

BE CAREFUL, a lot of teachers WON'T LET YOU USE IT

Get the TI Calc your child needs at the best price ANYWHERE (and I looked!). I'm not smart enough to figure out how to use this calculator, but finding this deal made me feel smart. I saved at least $20-30 over other stores, not to mention the aggravation of running around in the back-to-school frenzy. $.98 shipping is such a deal. Thank you WalMart!

TI Quality, WalMart Price

I love this calculator- it has a lot of great functions for advanced math. However, it's not ideal for High School math- if you have an Algebra I or II student, stick with the 84 Plus Silver. Definitely geared for the college-bound, math-oriented student. I'm a high school math teacher, if that validates my review.

Not for High School Algebra!

This calculator is a great product.....my problem is that I needed a graphing calculator for calculus and this calculator is not widely used.....the tutors didn't know how to use it. It's not as widely used as the TI 83 or TI 84 which is what everyone knows how to use. This one is different in how you input the data and is not very user-friendly. I know that it comes with a user manual (snore) I just don't have the patience to wade through 100+ pages to find f(x) and graph it. Forget the lim as h approaches 0....

Hi-tech

My son used this for his high school advanced math classes (as his teacher recommended) and loved it. It was easy to use and worked perfectly. I am now going to buy another one for my next son moving into high school since we had such a good experience on the first one. I was also told that this calculator will serve him throughout his entire academic career even into college. Wal-mart had the best prices both times.

Great for High School Math Classes
