> 3 dayI unpackaged it and turnwd it on and THIS SCREEN APPEARED. If you press EXIT, it will bring you back to the same screen. If you press EXE, nothing happens. If you reset it with the back button, you still come back to THAT screen. I,ve googled and tried EVERY solution possible but still, I ALWAYS come back to the same screen. I cant return because I am abroad right now so Ill have to stick with my out of the box broken calculator and 80 bucks less in my bank account. It does not even deserve one star. It should be less.

Greater than one weekVery hard to unpackage. DOES NOT have a CD or instruction manual. How am I supposed to learn the calculator. I am very seriously considering returning it for a refund. I own other Casio and TI calculators but this one is the worst. Buyer beware!

> 3 dayThis calculator is really good! I am an a level maths and further maths student and it is perfect for checking equations, stat functions, and helps you with trig graphs by drawing them! Amazing.

Greater than one weekI got this Casio graphing calculator for my 12th grade son, who is in both AP Engineering and AP Calculus, after he lost his TI-84 graphing calculator. The first day he used it he complained that it was backwards and that it was too different from the TI-84 to figure out (I assume he didnt bother to read the instructions)... but by day 2 he was a convert. After the steep learning curve, he now loves the Casio and strongly prefers it to the TI. Why does he prefer it? - A more user friendly interface, once he figured it out (he says if you arent already used to TI it would be even faster to figure out as it is more intuitive) - Faster processing - Easier navigation - Wider screen BOTTOM LINE: Different from TI but faster and, in the end, more intuitive.
