Top Customer Reviews
After a two hour session of pre-calc work, i've noticed the buttons have a faster and more accurate action than the 84, and while it feels a tad bit cheaper, it has a much more organized user interface and is a lot zippier, The backlight is a nice feature as well, although I don't see too much of a need for it as I do homework in good lighting. I like how their is a graphical menu as well, which I find makes it easier to get to where you need to be faster. Another nice feature is that it doesn't replace what you've typed in if you want to insert an integer or variable you forgot, which annoyed the hell outta me on the 84. Everything just makes more sense to me on this calculator. And if you want CAS, there's an add-on floating around the web that adds that feature. The only major downside is that there is no Mac version of the calculator software, but virtual pc can fix that in no time. Don't let that discourage you though, this is one kick ass calculator!
***A little warning to ex TI-84 users:
I found this calculator frustrating for the first ten minutes I used it while I was trying to figure out where everything was, as the layout is quite a bit different than the TI-84, but after that you start to realize just how well thought out this calculator is.
I still believe this calculator is one of the best choices available on the market. The polynomial solver and graphical integral solver are excellent time savers and can easily handle everything you need to do in Calculus, Chemistry, Physics, etc. If your teacher teaches TI, it won't take long to figure out the Casio parallel.
I'm now a 3rd year economics undergrad. I still have this calculator and still use it everyday. It works just as well as it did when I first bought it.
1. It gives exact answers for trig and square root problems (the TI only gives decimals). This is my #1 biggest problem with the TI84 Plus CE.
2. You do not need to open a seperate app to graph inequalities. The TI requires you to change to a different app, which is very clunky.
3. Handles fractions *way* better --> simplification, dedicated fraction key, fraction/decimal conversions.
4. You can use any letter of the alphabet to name a matrix (this is handy because it better supports matrix naming conventions). The TI only supports some letters.
The only issue I found with the fx-9860GII is the fact that fractional values displayed inside a matrix are *displayed* as decimal (but thankfully stored a fractions).
The TI-84 Plus CE had a much prettier display, however the monochrome display of the Casio was much easier to read. The TI did have one advantage over the Casio, it will display fractions inside a matrix.
I also prefer the mat finish on the Casio, as the super glossy finish on the TI84 Plus CE looks and feels cheap, and it attracts fingerprints.
Second, casio has better design. This calculator really looks better than whatever ti83 or 84. Also, this calculator displays pretty well. The true natural display. (Even if ti84plus silver edition has natural display, but it's not exactly the same as textbook. When i write the equation, it shows no natural display)
Third, casio fx9860gii computes faster than ti83 and 84. I have compared fx9860gii with ti84plus and ti84plus lost.
