Summary: Basically got myself a tiny machine here. I absolutely love this calculator, it's easy to navigate, long lasting battery life and very practical color display. It also doesn't lag except for the annoying graph mode where navigating seems kinda like it's re-plotting the whole graph again as you move around. That's the only drawback here.
Summary: I have had a couple of graphic calculators before including Casio's first three color screen calculator. This calculator offers a lot. It has a full color screen that is back lit and the keyboard laid out well. If you have used the Casio scientific calculators then this calculator will feel quite natural. The calculator is runs on four AAA batteries and lasts about 120 hours with the backlight on medium. The calculating features are excellent.
Summary: This calculator is allowed by all U.S schools (college included) I checked with my college director and yes they are allowed and they perform better than anything I have ever seen! Just read the description for details!
Summary: Casios are fast, beautiful, incredibly easy to use, and have the most efficient UI to ever exist in any graphing calculator. HPs are horrible, with an archaic UI that requires 2 or more steps to do exactly what the Casio can do. It's faster, the screen is excellent, math is displayed exactly how you would write it out on paper ... what's not to love?
Summary: First of all, this graphing calculator is not perfect. It has its flaws that to a certain extent might dissuade others from possibly buying it. However, the positive features of this device far outweigh the negative ones. Pros: 1. Big keypad. Not a lot of people might see this very useful but due to the large keypad, I hardly make any typos when I input numbers and variables. 2. eActivity.
The best calculator for higher level High School work and exams
22 April 2014
Summary: I work with the English exam system. Here, graphical calculators are allowed on most exam papers though there is a compulsory non-calculator paper at all levels too. And this is the best calculator for these exams. It's a Casio and it supports the same 'just as you'd write it' input and output that the cheaper Casios support (the FX 83ES+ is the 'standard' calculator lower down in most schools) and, being graphical, includes functions most users are shocked to find are...
Summary: Great calculator, shipping was on schedule as expected but that has nothing to do with the product itself. Casio did a great job, color looks clear and nice. Lots of functions out the box with the option to add and customize. The picture scape backround is nice for people who don't want to start at a white all the time. I purchased for around $80 on amazon great deal cause the ti84 plus comparison was $129.99 at the time plus shipping. I would recommend this product.
