The main differences compared to the tablet Apps are:
– speech output in various languages
– large, tactile buttons (a major advantage over touch screen apps, which also makes our calculators desirable for people with various fine motor challenges)
– adjustable contrast, invertible, backlit display
…and yes, they do have a graphing version.
In addition to the above features, another reason people purchase them is because of the requirement that various districts have prohibiting computers or web-connected devices (which is what smart phones and tablets are) into exams. We’re very proud of our calculators, but in the end that’s all they are — calculators, and that’s actually what many people like about them.google.com, pub-3447701155434117, DIRECT, f08c47fec0942fa0
