The solar absorption allows that the battery virtually never goes empty. This is very positive, since one must therefore make no battery change. You can speed up the charging by placing the calculator example, in the sun.
A big advantage of the calculator is that you can equations which have been set up, is still displayed on the screen and not disappear. Are you, for example 1 + 1 a, the equation is 1 + 1 shown in the top left and the result 2 in the lower right corner. Something like there are comparable products not what I find very positive.
It can work with roots, brackets, minus areas and much more. Buttons are easy to press, it gets stuck or not requires a lot of force to be pressed.
From a processing perspective, the calculator from Casio is also good, it is very handy and light.
I can recommend the calculator mainly in secondary 1. For 5 years, he was faithful to me and took me a long time accompanied by checks - This calculator is allowed also to most tests.
Therefore, of course, 5 stars!
