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.

Not that bad of a calculator. It graphs and calculate pretty good. However, It can be difficult to use because the key are confusing. Purchase with manual is better.

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.

I purchased mine for $49. Its suitable for any classes through college algebra. For trig you'll want to upgrade as it doesn't graph polar coordinates though it does convert rectangular to polar and back. If you needed to you could program it to input the (x,y) into a parametric graph and so display the results.

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 is a very limited calc. It dosen't have many functions nor programs. If you want to get a easy simple calc for like algebra this is good but if your in trig or calculus get a TI not this.

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

The product in general didn't match what i wanted, but I was at fault for that. There was some other trouble, and I think it would've been worth just paying for one at Wal-Mart or Target.
