Super performance and always approved

I have since min. 6 years this calculator (although its predecessor, but worse is the new probably not) I'm so super Duch my mechanical engineering studies.
The computer in my opinion 2 great advantages:

1. The very clear presentation on the display. Fractions are for example really displayed as a fraction, which avoids errors when typing.

2. It is not a programmable calculator, therefore it is guaranteed to be permitted in each exam. But that he passes as a simple calculator, the Casio fx-991ES can be incredibly much. You can expect the matrices, equations (not each, but some) can be solved by the TR and much more.

I am 100% satisfied with these TR and never had any problems, he was not admitted. But I then had always a great advantage in exams without graphing calculator with this.
