Average Reviews:
(More customer reviews)For me it was a choice between this calculator and a TI-83+. The fact is, this calculator has many more functions and is a lot more user freindly then a TI-83. For instance, unlike a TI-83 or TI-86 you can solve for x in an equation like 5=x^4+(x-3)^3. The HP39G divides each type of fuction into different "applets." There is one for stats, one for polar graphing, one for solving, and many others. The only bad news about it is that it's slow. It seems to take about the same time to do a very complex equation as to do 1+1. Don't worry though, you get used to the little delay-- it's still completly worth getting this calculator. It's cheap, there is plenty of games for it on the web, and it's fully featured.

Combining excellent usability with powerful features, the Hewlett-Packard algebraic graphing calculator is ideal for students, ranging from middle school algebra all the way up to high school and college level. Don't let the calculator's slim design fool you. Although it's compact and easy to slip in a pocket or desk drawer, the functions are meaty, and the high-contrast 131 x 64-pixel screen enables you to see more of your work.
Clearly designed for students, the calculator features a textbook mode allowing users to enter and view equations and expressions, electronic lessons adapted from textbook topics, and a split screen for side-by-side comparisons. And in the "Dang, that's cool" category, the calculator even features an infrared port enabling students to send data, equations, notes, and e-lessons to study buddies (no cheating, though!). The HP396 can also be hooked up to your PC or even an overhead display unit.
The keyboard is relatively friendly, featuring big keys with soft edges and wide key spacing for better keystroke accuracy. It runs on three AAA batteries and includes a one-year warranty.
