Super calculator with many features

I like the calculator of the functions was very good. Unlike my old graphics capability Casio this is reasonable display capable of breaking strokes, multiple fractures above the fraction bar are possible. In addition, I like that the root now extends down the root and is indicated not only at the beginning. All visual enhancements, the anticipate that make it much easier.

Battery and solar cells make this power pleasant, only a change of battery is not possible without using a screwdriver. Anyone who expects only in a dark cellar, might begin to think. Although I appreciate the button battery is master on average use even their year.

What bothers me, and why there is no 5 star is processing. My keys with the numbers are all wrong, there's too much play! Also a pressure point I would have liked.

Nevertheless, he is a balanced, meaningful accompaniment for work, school and study for 20 euros.
