I bought this item for my son . He loves this product very much.The functionalities required for every math student is available in this calculator.I would love to recomend this for any math student.
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).
This calculator takes a little getting used to, but it, so far, has helped me tremendously in my AP Calculas class once I kinda got the hang of it. It has many more functions than a TI-83 Plus does that you use regularly in the higher-level classes. I would recommend it for anyone that's considering it.
Like many first time users the calculator takes time getting to know. But overall I have to say the calc. is the best available on the market. I would recommend it to anyone.
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.
I am a mechanical engineering student and i found this calculator very useful for my classes. It has lots of good options to use to solve problems. I also downloaded ME Pro which has tons of mechanical engineering formulas, and information that is extremely helpful.
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.
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.
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.
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.
