Texas Instruments TI-84 Plus Silver Edition Graphics Calculator

It's a great tool, especially for college students. It has some very helpful calculus functions, and is perfect for classes like chemistry when graphing sets of data. It's a little pricey, but a wise investment all the same. I recommend this product over the TI-83 because it has over double the memory capacity, and has more calculus applications available. It is a little bit more expensive, but in this case, you definitely get what you pay for.
Accessories, such as downloadable programs, faceplates, and slide covers are available for order through the Texas Instruments website, which is very helpful. I got bored and decorated my calculator, as shown in the picture.

Great product useful very much for college student.

I bought this calculator for my College Algebra class and used it all the way up through Pre-Calculus and on through Calculus 3. I never needed to buy another calculator throughout my whole college career. I would spend the few extra bucks on this calculator and ensure that you'll get plenty of use out of it through all your courses.

Bought this for my 17 year old son. You can connect it to the computer. It has games. You can take it to the ACT exam. It's a little more expensive than other models, but well worth the price for all the extra "bells and whistles" that come with it.

This product was bought as a gift for my daughter, who is in college. She loves it. She loves the programs and games.
