Casio FX-7400GPLUS Graphing Calculator

The calculator has single- and double-variable statistics graphing, including box and whisker plots, median-median lines, histograms, scatter plots, X-Y lines, and broken lines. It also offers single- and double-variable list-based statistics calculations including descriptive values and linear, quadratic, logarithmic, exponential, and power regressions. The list editor creates, edits, and manages six separate data lists, and the data can be exchanged between list and table modes. With the sketch feature, you can draw points and horizontal and vertical lines on any graphic display.

There is 8 KB of available memory which can store up to 38 programs and allows for user-defined programs and formulas. In case of accidental shutoff, the memory is maintained. The calculator takes two AAA and one lithium-ion backup battery and comes with a hard, protective slide-in case. The Casio FX7400G PLUS comes with a one-year limited warranty. --Dana Van Nest

While my class mates were worrying about how to get their TI's to work I was working on the problems. Even though I've moved to the Casio AFX 2.0, I keep it for a backup. When my buddy isn't borrowing it...

This calculator has many good features. Large enough for keys to be easily used, but fits in a shirt pocket. Uses two cheap AAA bstteries with a button battery for memory backup. It has a detailed instruction book, But the MEMORY is next to IMPOSSIBLE to access. The calculator does not even use the word memory, but uses the word list. It goes in to great detail how to manipulate the data in the list, but does not have a store or save and a recall button I spent 2 days trying to figure it out, and finally took it back. The HP9g that I replaced it with was easy to enter and access memory.

studying A level maths i thought a graphic calculator would be fairly useful, and it was for a while. But with its poor diferentiation capibilitys and total lack? of intergration one. My advice if you were thinking of buying one of these is spend a little extra money and get a Ti-83

Other than students few need, or can use graphing calculators.
Although this calculator is advertised as being useful up to and including the calculus it is best used in Pre-Algebra and Algebra I. This is a very inexpensive graphing calculator and is, thus, very slow, the screen is pretty hard to read and the instruction book not only hard to follow and very demanding but printed on paper so thin that one can read the second page through the first.
After buying this calculator neither my 14 y.o. nephew nor I know just where it `fits'. He reports that its slowness yields it fairly unhelpful in class. I prefer the entry system of Hewlett Packard RPN.
We conclude that this calculator is best used for simple non timed investigation of numbers and their relationships to one another as in 2 + 2 = 4
A good pre algebra calculator, a pretty good algebra calculator ad for the price ... unbeatable.
A good choice when calculator theft is a real possibility.
