Casio fx-9860GII Graphing Calculator, Black

The calculator did not work. Trash.

Form factor is comparable to a TI-89. Some functions require several keystrokes to access. But after 2-3 months of use, Im going back to my HP Prime which is both functionally and ergonomically superior (and also significantly more expensive). All in all, dont think you could do much better for the money. Ordinarily Id recommend this for HS math students, but those classes are often built around TI calculators so this would probably mean you were swimming against the current. For college level math courses you wont even be allowed a graphing calculator... and this is where most Casios excel. The FX-115ES (and the new 991EX) are extremely robust scientific calculators. But if you go on to study circuits and upper level engineering topics, then this Casio 9860gii sits in a sort of nowhere-land -- It isnt as powerful or usable as youd like, but also not as simple or cheap as some of Casios great scientific calculators.

as expected!

It met my expectation and so far so good.

A couple of years ago I had a TI-89 Titanium that was later stolen. I had to get a new graphing calculator for my precalc class, but TIs are over $100.00. During high school I had at one time replaced my Ti-30 whatever with a Casio fx115 and thought it was a lot more calculator for less money. This calculator is at highest $99 and I bought it here for $55. So far I am having the same experience as before. The calculator is much more user friendly, with fewer sub-menus. My precalc book is written with an index specifically for TI-84 and I can perform every function faster than anyone in my class, and they have instructions in the text book how to do it. To date there is only one problem that the keys were not intuitively labled, but the calculator comes with a CD ROM instuction manual (great for the environmentally conscious) and all I did was type in the search bar what I wanted to do and issue resolved. Unlike the TIs which it took me a week or more just to learn all the menus, this calculator has several more function keys for faster navigation. The screen is wider and sharper than TI and it has a back light. Why TI graphing calculator is the standard has got to be nothing but beauracracy. I wont even consider a TI if I ever need to replace this calc. (I am actually girlie4gzuzs husband who bought this calculator with her account.)
