Casio Graphing Calculator Review

Average Reviews:

(More customer reviews)This is the best graphing calculator you can buy for under $100, period.I teach mathematics, and have used everything you can imagine, from TI to HP to Sharp and Canon, and this is the fastest sub-$100 graphing calc out there, nearly twice as fast to draw functions as the TI 84, which runs at least $20 more ($35 more at educational prices).It is also faster than my first generation TI89, and unlike the TI89, is legal to be used for ACT and SAT tests.
The menu navigation takes a few minutes to learn, but then it is easy, and much faster to do most things, compared to the TI and other calcs.For instance, it takes four button presses to find the zeroes of a quadratic, rather than the nine (or more) it takes on a TI.

The USB port means you can use it to write to a computer screen with the downloadable software, as well as use the computer to write to the calc; (you must supply the USB cable), and you can also hook to other Casios with the included non-USB wire.
The manual is online, or in a CD included with the calculators I bought. (is that still true?)
The screen isn't the best around, but is plenty good enough for my 45 year old eyes.
If you want a calc that will get you through anything from Algebra to Calculus and beyond, this is the one.
